Fetal heartbeat. What should be the palpitations of the fetus in the early periods of pregnancy? Fetal heartbeat under week week 164

The frequency of heart abbreviations is an integral indicator on which many factors affect: blood saturation with oxygen, hemoglobin level, the anatomical features of the heart, the effects of hormones and the vegetative nervous system. That's why by the nature of the fetal heartbeat, it is possible to judge its viability.

You can determine the heartset of the fetus by many methods: auscultation with the help of an obstetric stethoscope, cardiotocography, when conducting an ultrasound. Each of these methods has its advantages. Regular monitoring of the heart activity of the fetus allows you to sometimes change the tactics of pregnancy and childbirth, to make responsible decisions, thanks to which the baby can be saved.

When the embryo appears heartbeat?

development of the heart of the fruit

Heart formation begins for 2-3 weeks of intrauterine developmentThat is, at that time, when a woman is not even suspected of possible pregnancy. During this period, the heart has the shape of a simple tube, which, at the beginning of 3-4 weeks, begins S-shaped bending. That is why at this stage of development, the heart is called Sigmid.

After 4-5 weeks of the gestation, the primary partition between the atrium is formed, as a result of which the heart of the embryo becomes 3-chamber. It is at this stage that the first heart abbreviations appear. However, in order to reliably register the heartbeat of the embryo at the 5th week of pregnancy, an ultrasonic class apparatus is necessary. But it is important to remember that in the absence of special testimony, the implementation of ultrasound at such an early term is unreasonable and not recommended.

In this regard, indirect confirmation of the normal development of the embryo and his heart on the 5-6 week of pregnancy is to determine the level of the hormone (chorionic gonadotropin) in dynamics, after 2-3 days. On 5 week, the level of this hormone ranges from 1000 to 3100 MME / ml. With normally developing pregnancy in the early periods, the level of hCG every 2-3 days double. But it is necessary to know that the definition of HCG is reliably up to 10 weeks of pregnancy, because in a later date the level of this hormone begins to fall, which is the physiological norm. Therefore, this method of diagnosis is relevant only at the very beginning of pregnancy, as an alternative to ultrasound in very early time.

Fetal heart rate for pregnancy weeks

A very important aspect in assessing the heart activities of the embryo is the knowledge of physiological norms at a certain week of pregnancy. (Contrary to misunderstandings, for future boys and girls they do not differ!). For convenience, all these data are collected in the table:

Week of pregnancy	Fetal heart rate on weeks	Methods of determination
5	90-110	-
6-7	100-130	Ultrasound diagnostics
8-9	130-150
10-11	130-160
12-13	140-170
14-15	140-180
16-17	140-170
18-19	130-170
20-21	140-170
22-23	130-160	Cardiography, on ultrasound
24-40	120-160	Ultrasound diagnostics, CTG listening with a stethoscope (heartbeat heard from 27-28 weeks of pregnancy)

What is the method of diagnosing the heartset of the fetus most informative?

There are quite a few ways to keep track of the work of the fetus heart, and each of these methods has its advantages.

Listening to an obstetric stethoscope

This is the easiest and most affordable way to determine the reductions of the health of the fetus. The obstetric stethoscope is a simple funnel. In order to hear a heartbeat, a wide part of the funnel is tightly pressing to the front abdominal wall. Such a simple method is effective only in experienced obstetricians. After all, to listen to the tones of the heart, you need to know where to put a stethoscope. To do this, before auscultation, the doctors conduct an outdoor study of the position of the fetus: determine the presence (part for a small pelvis), the position (the arrangement of the backrest on the right or left) and the view (turn back or backward) fetus.

listening to a stethoscope and an electronic device for domestic listening of various sounds published by the fruit

Depending on the position of the baby in the uterus, the heartbeat is well listened to different places:

location of points for listening to the palpitation of the fetal stethoscope

Auscultation of the heart of the fetus with a stethoscope is an excellent method that came to modern obstetres from ancient times. For auscultation, only a stethoscope and competent specialist are needed. But this method has one significant disadvantage: human ear can recognize the tones of the heart, as a rule, not earlier than 27-28 weeks of pregnancy. On earlier deadline, it is practically useless. And with the pronounced obesity of a woman or a swelling of the anterior abdominal wall (with gestosis), hear the heartbeat can be even later, on October 29-30. For this reason, other methods of diagnosis are in the first half of pregnancy for registration of heart activities to the fore.

Cardiotokography

- This is a method for registering the cardiac activity of the fetus using a Uz-sensor. The data obtained from the sensor is converted into a cardiomonitor into the heart rate, which are displayed on paper as a graph. This method is very good the fact that the record can be quite long (about an hour, if necessary, and more), and you can evaluate the work of the fruit heart for all this time. In addition, the undoubted plus is the simultaneous registration of the tone of the uterus by the second sensor, which is called "strain gauge".

Rules of registration of KTG:

During the study, the woman should lie on the side. If pregnant will lie on the back, then the results cannot be considered reliable, since in this position the uterus can squeeze the hollow vein located under it, as a result of which the royal and placental blood flow is disturbed. This condition is called the "Lower Half Vienna Syndrome", which may cause a disruption of the rhythm of the fetus.
The ultrasonic sensor is placed on the front abdominal wall of the pregnant in the place of the best hearing of the heartbeat, it is fixed with elastic ribbons. Before starting the study, it is necessary to apply to the surface of the gel sensor to improve the conductivity of the signal.
The sensor for registration of the tone is better to install in the bottom of the uterus.
Modern devices are equipped with a remote control with a button that you need to press a woman during a study when a fetal motion sensation. This is a very important diagnostic sign, as it is possible to establish which violations of the rhythm occurred during the movement of the fetus, and which are alone. This technique is called a non-stroke test, as in response to the movement of the fetus, rhythm occurs.
The cardiotokograpograph also is also equipped with sound instruments, with the help of which a woman can hear the heartbeat of her baby. In most cases, it acts soothing on pregnant women.
The study should be carried out about 40 minutes, no less. An increase in registration time is not prohibited, but a less short study is not always informative and does not reflect the full picture of the state of the fetus.
This method can be applied from 22-23 weeks of pregnancy.
Only a doctor can decipher the results of the CTG.

Echographic Study (Ultrasound)

The ultrasound method is very informative, undoubtedly a plus is the possibility of observing the heart rhythm already in the earliest period of pregnancy, when other methods are ineffective. Thus, in the first half of pregnancy, this is the only method for evaluating the work of the cardiovascular system of the fetus. With the uncomplicated course of pregnancy, ultrasound examination is carried out three times at appropriate terms (10-12 weeks, 21-23 weeks, 31-32 weeks).

Cardiac rhythm assessment is carried out in a complex with other important studies. However, if necessary, it is possible to investigate the frequency of abbreviations of the heart, as well as to carry out certain unresponsive tests and more often (for example, with, impaired uterine-placental blood flow) in order to monitor the state of the fetus in the dynamics and compare the obtained shown with the previous ones. Often, such studies are carried out after a certain treatment to assess the effectiveness of therapy.

Cardiointervalography

This method is used very rarely and only needed in cases where it is necessary to study the heart rhythm of the kid in controversial situations or with severe pathology. This technique is the ultrasound registration of the heart of the heart for a long time (at least 60 minutes).

This information is fed to the computer that conducts a detailed analysis of all indicators:

The cardiointervalography method is very informative and often helps to figure out the true causes of heart rhythm.

Causes of Fetal Heart Rhythm

Sometimes after the study it turns out that the heartbeat does not meet the adopted standards. This situation needs to be treated with due attention and find out what reasons it happened.

Factors leading to rapid heartbeat (tachycardia):

at the mother.
Reducing the level of hemoglobin in the fetus (for example, when) causes the flow of blood flow, as well as a compensatory reaction in the form of tachycardia.
Placental insufficiency.
Mother bleeding (for example, with placenta detachment).
Raising temperature in a pregnant woman (feverish state).
Inflammatory process in the fetal shells (amnionitis).
Reception of some drugs. For example, a often used medicinal product in the obstetrics "Ginipral" can cause tachycardia not only in the mother, but also the fetus. In addition, drugs that block the influence of the parasympathetic nervous system (for example, "atropine") are also able to cause the healing of heartbeat.
The pathology of the umbilical cord (, curtain, etc.).
Acute intrauterine hypoxia can cause a sharp increase in the frequency of reducing the heart of the fetus until 200-220 per minute.
Pup loop loss.
Increased fetal pressure.

Causes of fetal heartbeat deceleration (bradycardia):

Long-term foundation of a woman in a back position at which the lower hollow vein is compressed.
Reception of drugs blocking the sympathetic department of the nervous system, for example, "propranolol".
Pronounced disorders of acid-alkaline equilibrium in the blood of the fetus with serious exchange violations.
Some abnormal development of the fetus.
In the blood of the mother and the child, which leads to a violation of the rhythm of the heart and the appearance of bradycardia.
Prolonged compression or node of umbilical cord.

Each of these reasons is very serious and often requires treatment, and in some cases even emergency delivery in the form of cesarean sections.

Is it possible to listen to heartbeat at home?

Some parents are wondering if you can hear the heartbeat of the baby at home, not referring to the specialists, if you use the usual phonedoscope.

Along with traditional methods, various gadgets for pregnant women are gaining popularity, the essence of their work in general is similar

Of course, this method can be used. But be prepared for the fact that until 21-22 weeks you will not hear the heartbeat. In addition, you will need to be able to distinguish between other sounds from the health of the fetus: the pulsation of the abdominal aorta pregnant, intestinal peristalsis. On average, the heart of the kid beats more often than 1.5-2 times. For convenience, it is possible to consider a woman's pulse at the same time during listening, so as not to confuse the rhythms of her and the baby.

Determining the floor of a child heartbeat: myth or reality?

There is a stereotype among the population that in the frequency of a heart cut can be found in advance who will be born: a boy or a girl. It is believed that the boys have a heart beating a little less often than girls. But is it possible to rely with confidence for this data?

It is no secret that many factors affect heartbeat, for example:

Motor activity kid;
Time of day (sleep or wakefulness);
Individual features of the innervation of the heart muscle and the conductive heart system;
The effect of hormonal factors;
The level of mother and fetus;
The presence or absence of certain pathological conditions during pregnancy (hypoxia, severe gestosis, bleeding, rezv conflict, etc.).

an example of sample sampling in fruits - boys and girls. As can be seen, the values \u200b\u200binside the floor are distributed without explicit patterns.

Given such a large number of factors that change the heart rhythm, is it possible to evaluate the frequency of heart abbreviations only from one position - the floor definitions? Certainly no. Moreover, a study was carried out at which the sex of the child was determined solely by the nature of the heartbeat, and the accuracy of this technique was only 50%, which means that it is equal to the banal probability theory: one of two options. In this way, learn the sex of the child only according to the evaluation of cardiac activity is not possible.

Cardiac rhythm is an indicator of many processes occurring in the fetal body. In the structure of the heart rhythm laid a large amount of information.

In fact, the heart rate reflects the complex of protective and adaptive reactions of the fetus to any influences and changes. Of course, the evaluation of cardiac activity in the intrauterine period is extremely important. The presence of a large number of techniques, as well as their availability, is very simplified by the process of observing the state of the fetus.

Despite the development of complex, invasive techniques, allowing to thoroughly study the state of the fetus, their danger is sometimes very high and unjustified. For these reasons, all female consultations, as well as the maternity hospitals are equipped with cardiomonitors, ultrasound devices, and all obstetrics practically "do not part" with a stethoscope, because it allows us to carry out due control over the heartbeat, without hurting him.

The heart rate (CSS) of the child is one of the important indicators of the normal course of pregnancy. You can listen to the head of the children's heart in 6-8 obstetric weeks after conception during ultrasound diagnostics. As the baby grows, the norms of the CSS change. Developed special tables from which you can find out the value of this indicator. What characteristics are important when listening to the heart of the embryo and for what reason there are deviations?

When does the perfume begins to beat the heart?

The heart of the fetus is one of those important organs that are formed and function from the first weeks of intrauterine development. Registration of its rhythm is one of the reliable criteria for the heart activities of the fetus:

early knock - evidence that the fruit is growing and developing;
the CSS values \u200b\u200bin different moments of pregnancy differ, which allows you to constantly monitor the development of the baby;
according to the features of heart rate (rhythmic, arrhythmical, clear, muffled), you can identify intrauterine pathology and take the necessary measures to preserve pregnancy.

The heart laying occurs on 2-3 weeks of the embryo. Initially, it has a shape of a small hollow tube and over time is transformed into a miniature full-fledged organ. The first shocks are observed on the 4-5 week. Heart begins to beat gradually, soon his rhythm is being established. Initially, the body takes 10% of the total area of \u200b\u200bthe body, by the end of the navigation, the indicator is reduced to 1%.

How can I hear a baby heartbeat?

CIS of one baby or twins can be fixed by the following methods:

Ultrasound diagnostics. The ultrasound is carried out from 4-7 weeks, it allows you to determine the size of the organ, listen to the tones, identify rough defects. If necessary, it is assigned to 12, and 20, and at 23, and at 32, and in 37 weeks.
Listening through a stethoscope. Performed by an obstetrician from 20 weeks to assess the timbre, frequency and rhythm of the knock, noise definitions.
Echocardiography. It is held from 20 weeks if suspected the malformations of the fetus. Allows you to study the bloodstream, the structure of the muscular organ. The studies of the study are considered to be the age of 35 years old, the birth of children with heart patterns in history, infectious diseases in a woman.
Cardiography. The method is effective from the 30th week. It helps determine the degree of oxygen starvation by the nature of the pulse and the movements of the crumbs. These parameters fix sensitive sensors and output the result in the form of a graph.

If pregnancy proceeds normally, the test ultrasound Woman should do three times: at 11-14, 18-21, 30-34 weeks. Listening to a stethoscope occurs every time with a planned visit to the doctor from the second half of the gestation in order to determine the rhythm and heart rate of the fetus. An obstetrician first determines the position of the baby in the uterus and then applies a stethoscope to the belly of a woman closer to the fetus head from his back. The frequency, rhythm and soundness of the tones is estimated.

Cardiomonitoring is carried out on 30-32 weeks. In the pathological course of pregnancy (multi-way, hypoxia, gestosis), the study is carried out as often as it is necessary to determine the state of the child: by 32, 35, 38, 40 weeks. The KTG apparatus is used in childbirth in order to determine the knob's heart knock, the contractile activity of the uterus.

During the first four weeks of pregnancy, the palpulation of the fetus is not listened. To determine its viability and prosperous pregnancy, the level of chorionic gonadotropin of man in the urine is found out. In the absence of conception, the hormone level is not higher than 5 MME / ml. If the fruit is developing correctly, the HCG indicator will grow and will be (MME / ml):

1-2 obstetric weeks - 25-156;
3–4 – 101–4800;
5-6 weeks - 2560-82300.

In what cases is required to count the Church of the child in the womb?

Head of the heartbeat or twins is aimed at observing the toddler's growth. Counting reductions of the heart muscle makes it possible to monitor the formation of the fetus during the period of pregnancy and monitor the process of the delivery of 38-40 weeks.

CHSS counting makes it possible to identify a number of pathological conditions:

Vices of the heart. With anomalous development of the organ, the rhythm change is noted - arrhythmia is observed. What caused an anomaly? This allows us to find out additional surveys. Also about the pathologies of the body says the presence of extraneous noise.
Failure to pregnancy. The method allows you to identify the fetal death in the womb in the early stages. If with the size of the embryo 4-5 mm and there is no heartbeat in 6-12 weeks, the level of hCG is close to zero, it means that the embryo does not develop.
Hypoxia fetus. Insufficient oxygen intake is compensated by more intensive blood flow and increasing heart rate. In hypoxia, the heartbeat is weak, slowdown, its indicators are below the norm.

The rate of heart rate of the fetus for weeks (table)

The indicators of CSS change in the womb are reflected in the table:

Obstetrician week of pregnancy	Heart rate (Ud / min.)
4–5	90-120
6–7	100–125
8–9	120–150
10–11	125–160
12–13	130–170
14–15	140–180
16–17	135–170
18–19	135–165
20–21	140–170
22–23	130–160
24–41	120–160

The greatest EHF values \u200b\u200bare noted on the period of 8-12, 14-15 weeks of tooling. Then they decrease smoothly. By 13-15 weeks, organs and systems are formed finally, from this time the active growth of the fetus begins. At the end of the CSS period is 120-160 beats per minute.

The frequency of the child's heartbeat during the intrauterine development depends on a number of essential factors:

physical activity;
hemoglobin level;
tone of the uterus;
emotional state of a woman;
pathology gestation: rezv conflict, bleeding;
individual features of myocardium;
period: Sleep or time of wakefulness.

If a woman is hagging twins, the heart rate of each kid is usually located on the lower boundary of the norm. Good indicators of each of the children by the time of birth - 110-150 beats per minute. About tachycardia shows the parameters of 180 beats per minute and more. Bradycardia in one or two kids is diagnosed with a pulse of 100 beats per minute and less.

CSS does not depend on the floor of the child. On average, the baby's heart in the womb beats 2 times more often than his mother. However, there is a belief that the heartbeat of boys is 120-150 beats per minute. In girls, the figure is higher - 150-170. It is believed that in male children, the character of heartbeat is measured, and girls are more chaotic. Scientifically this information is not confirmed. To find out to know the sex of the child during the ultrasound from the 18th week. The error in determining is 10%.

What characteristics are taken into account when listening to the Church of the baby?

When examining the work of the edge of the embryo, one of the above methods, the doctor draws attention to such indicators:

Heart rate. The rapid beat of the child's heart is a symptom of tachycardia. Rare and muffled knock is observed in bradycardia. Both states need close observation and correction after finding out the causes of the occurrence.
Rhythm. The norm is equal temporary intervals between heart blows. Vices of cardiac valves, fetal hypoxia, intrauterine infection and other pathologies lead to arrhythmia.
Character of tones. Clear and ringing strikes - evidence that the heart is great. If you are heard deaf, blurred shocks, pathology is possible.

What can alarm deviations from the norm?

The main criterion for which the doctors are focused when evaluating the intrauterine development of the fetus is the frequency of heart abbreviations. As a rule, an increase in this indicator is revealed compared to the norm, and this is not as dangerous as a slowdown.

The increase in the heart rate is the evidence of oxygen starvation of the fetus, which may arise for the following reasons:

malformations of intrauterine development;
anemia (in mother or fetus);
uterine bleeding, threat of miscarriage;
the acute diseases of the mother, in which intoxication is observed, heat;
nodes and abnormal cord length;
placental insufficiency;
intrauterine infection;
gesters and any pathology that leads to a circulatory disorders in the placenta;
hereditary factor.

Reduced heart rate compared with rates (bradycardia) - evidence of the following violations:

pronounced hypoxia;
increased maintenance of potassium in the blood of the mother;
improper metabolism in the parent and children's body;
heavy fruit heart disease.

You should not exclude errors in the study of the pulse, the cause of which can be:

the location of the placenta in the field of the front uterine wall;
multiple pregnancy;
multi-way;
mother's obesity;
increased child activity.

The cause of a short-term slowdown of the fetal heartbeat or non-cultural cuts of the heart muscle can be a long position of the mother on the back during the examination. If pathology is revealed, in many cases there will be a root separation by cesarean section. In case of difficulties in research, arrhythmias or other or deviations, the doctor will prescribe a repeated time for the survey, send to additional analyzes.

When identifying the causes of pathological changes in the heart rate will be prescribed treatment. It depends on the period of pregnancy, the nature of its flow, the degree of severity of pathology and other factors. Usually, pregnant women are hospitalized or sent to day hospital.

Therapy includes the reception of medicines, vitamin complexes, a decrease in mental and physical exertion, the prevention of stress. Regular control of the state of the fetus is carried out. In severe situations, cesarean section is performed.

The table of indicators of the heart rate is informative, but only a doctor can draw conclusions about the state of the child on its basis. The task of the mother is clearly followed by its recommendations, if necessary, go through the necessary surveys and prescribed treatment.

When a representative of the weak gender receives a positive response of a pregnancy test, she has a number of questions and doubts. So, a woman thinks how quickly her tummy will grow. Future mom is interested in his own well-being. Also an important question that worries a woman is the definition of the floor of the future kid. Boy or girl will be born? This article will tell you about how the definition of Paul is being done according to you learn the features of the rhythm of muscle cuts in boys and girls. It is also worth saying that 12 weeks are determined more accurate than before or later.

Floor child: general formation description

At the time of fertilization of the egg in its cavity penetrates only one spermatozoa. It can carry genital geamnets with x or in chromosome. Accordingly, the floor of the future kid is laid at this moment. The embryo during this period was not yet completely formed, and you will not be able to determine its sexuality.

Approximately the reproductive organs begin to form. In girls and boys at this moment they look equally. However, in the future there will be a strong transformation, and completely distinct genitals will appear.

Definition of the floor of a child in heartbeat in the womb

To begin with, it is worth saying what values \u200b\u200bexist, and how it is reflected on the gender of the baby.

Rhythm abbreviations.Boys boast of measured and clear rhythm. Their heart is knocking smoothly and evenly. At future girls, the muscle is reduced chaotic and excitedly. It seems that the girls are still in the womb of the mother are more emotional personalities.

Dependence on the maternal pulse.It is believed that the boyish heart knocks not only clearly and monotonously, but also significantly louder. Also, all reductions coincide with the maternal pulse. Girls do not have any dependence on the head of the heart of the parent. The tones of the muscle cuts of future daughters are more muted and not so clear.

Belly side.There is a version that a boyish heart knocks on the left. If the sound comes to the right, then the girl will most likely be born.

True or myth?

Can I believe the above-described patterns? Many use this way to find out as early as possible who will be born. However, the probability of the correct response is only 50%.

Doctors argue that the study of this method is no more than simple entertainment. Officially, such a technique is not recognized and has no reasonable confirmation.

How can I calculate the heart rhythm?

So, you are already known how the definition of the sex of the child in heartbeat is made. The options proposed above can be grouped and combined with each other. However, to make any conclusion, you must first calculate the baby in the womb. This manipulation can be carried out in several ways:

using a stethoscope (this option is suitable for measurements after 12 weeks of pregnancy, when a critical organ leaves the boundaries of a small pelvis);
using the tube (this method is used after 20 weeks of pregnancy, when the fruit is already quite large);
cardiotockography apparatus (research and measurements are made after 30 weeks of pregnancy);
with the help of Doppler (the device is used after 15 weeks of the child's development and externally resembles a miniature ultrasonic apparatus);
during the ultrasound (diagnostics can be carried out in the earliest period of pregnancy).

How to determine the sexuality of crumbs in 12 weeks?

If you want to learn half a child in the heartbeat in 12 weeks, then you need to conduct an ultrasound study. During diagnostics, the specialist may include the sound of the device. This will not only calculate the number of abbreviations, but also hear them.

Also, the medic can display the curve line of the cardiogram. Special program makes metering and counting heartfills. The work of technology allows you to avoid the error that could be when counting the blows by a person. So, how to determine the sex of the child in the heartbeat in 12 weeks?

What is characteristic of girls?During this period, the frequency of muscle cuts is in the range from 150 to 170 beats per minute. The knocks are fast and muted. Rhythm chaotic, and you are hard to catch monotony. Also an experienced specialist can have its own ways to determine the floor of the kid on the knock of his heart.

What is characteristic of boys?The head of the heart is observed from 120 to 140 times per minute. The sound is clear and loud. Reducing more similar to the heartbeat of the adult heart. Also determined by special rhythm. With the increase in pressure or excitement of mom, the heart of the crumbs begins to beat faster. This pattern is present in most cases.

Summing up and a small conclusion

So, now you know how to determine the sex of the child in the heartbeat in 12 weeks. Remember that with an increase in the period, the number of muscle cuts gradually decreases. By the time of birth, it reaches 100-120 blows per minute.

Also too early measurements can lead you to an erroneous result. In the period from 8 to 10 week, the development of the kid, his heart can fight with a frequency of up to 180 shots per minute. At the same time, the boys are practically no different from the girls.

Remember that more accurately find out the floor of the future child will help an ultrasound study, which is held after that is why it is not worth it too trusting to treat all the ways of early diagnosis of the child. Successes to you and the birth of healthy kids!

Each mother wants to hear the sound of the heart of his future kid as soon as possible. Of course, with this one of the most pleasant and exciting experiences. After all, if you hear how the heart beats, it means that the fruit grows.

But the sound of the heart of the fetus not only suggests that the new life is actively developing, but can also give a lot of important information about the health of the kid.

The question is when the palpulation of the fetus appears, relevant for each future mommy, like such an important moment, like the movement of the fetus during pregnancy, the norm of which each woman can be different. The heartbeat can also be brought to different times for the first time.

Women who are interested in what time the heartbeat appears, it should be understood that the heart of the fetus does not begin to beat at one moment. When the laying of this organ begins, the part of the fabric, which subsequently develops into the ventricles of the heart, makes contracting movements. Of course, the period when hears the heartset of the fetus on the ultrasound, comes later.

The gynecologist will tell about what week this sound is heard: it can sometimes be heard in the earliest time. With what Hgch. It is also audible at what time is "visible" on the ultrasound of heartbeat depends on the power of the apparatus, which conduct a study. Using the usual abdominal ultrasound sensor, the doctor can hear the heart blows already on the period of 5 weeks. And with the help of a vaginal sensor, the blows can be heard already in 3-4 weeks, that is, immediately after the heart begins to beat the fetus.

The heart rate depends on what week a heart beats. At different times of pregnancy, it is different.

When the term is 6 weeks - 8 weeks, the Fetal CIS is equal to 110-130 beats per minute.
In the period from 8 to 11 weeks - the heart rate can increase to 190 shots.
Already from 11 weeks the frequency is 140-160 shots.

The table below indicates the frequency of heart abbreviations at different times of the fetus. It is very easy to understand how many blows the baby must be fighting in different periods of pregnancy.

Fetal heartbeat table for weeks:

Those who are interested in the CSS Table of Fetal for weeks by the sex of the child should know that both girls and boys have the same heartbeat.

The doctor estimates not only the fetal heartbeat on weeks, but also additional factors, such as the child's activity phase, mother and fetus disease, the time when the frequency is determined, etc.

If the fetal heart rate is violated for weeks, it can be associated with different reasons.

Why violated heart rhythm

If the heart rate is less than 120 beats per minute

The causes of weak heartbeat in early periods can be associated with different reasons. It can be fixed on a small period - up to 4 weeks. On 6 week, the pulse of the embryo can be 100-120 shots. Pulse 130 beats also testifies that everything is fine with the baby. But if very low heartbeat is fixed, less than 80 shots, then there is a risk of loss of pregnancy.
If ultrasound is 12 weeks and more indicates a low heartbeat, it may be due to chronic hypoxy fruitbut Or his reaction to the fact that the Pupovina is squeezed. If the heartbeat is 120 beats per minute, what to do, must tell the doctor, guided by the research results.
Before childbirth, weak rhythm can be evidence of acute or chronic hypoxia of the fetus, as well as the compression of umbilical cord during contractions.

If the pulse is 160 shots per minute exceeded

At the first weeks of pregnancy, this is usually the option of the norm, but in some cases indicates a violation of placentating.
After 12 weeks of pregnancy, the fruit can react to its own movements or stress, experienced by her mother.
The fetus in the later dates may be a consequence of chronic hypoxia of the fetus or a reaction to a movement or a fight.

Sounds deaf, tones are poorly listening

If listening is carried out in pregnant women in early time, it may say that the term is too small or the study is carried out by a faulty sensor, or the device for listening is outdated. Also, this is possible if mom has. But also poorly listening tones in early terms can be evidenced by the fact that the kid, blood vessels.
After 12 weeks, the deaf tones can be heard if the mother has obesity, as well as feto placental insufficiency , prediction (if the placenta is located on the front wall), lowland or multi-way. Sometimes the deaf tones are fixed, if the location of the child in the womb is uncomfortable for listening. However, heart or vessels are also excluded.
In the later colors, such a phenomenon indicates that active contractions began or hypoxia of the fetus.

Heartbeat is absent

In the earliest dates, the sound of the heart is absent if the term during listening is very small, or an outdated sensor is used. However, sometimes it is evidence that pregnancy froze or begins.
For a period of 12 weeks, as well as in the last weeks, the lack of sound of the heart can be either evidence of the wrong place of auscultation or damage to the KTG sensor, or say what happened antenatal fetal death .

The presence of the heart of the heart and the fetal heart rate is determined during pregnancy with a certain goal.

To establish that pregnancy develops

After the future mother spent a pregnancy test, and he turned out to be positive, the woman goes to the hospital to pass an ultrasound study. Modern ultrasound devices make it possible to hear the edge of the heart of the embryo already at the first study - on the 4-5 week. But if on the first ultrasound of the heart of the child is not heard, you should not panic. As a rule, when re-conducting the procedure you can hear the expected sound. However, sometimes heartbeat never appears, the fetal egg deformation occurs. This condition is defined as a frozen pregnancy. In such a situation, a drug interruption is carried out with the help of special drugs. If such a situation happened, then the woman is not recommended to be pregnant about six months after that.

To evaluate the development of the fetus

There are clear indicators of what is considered normal heartbeat on what time. That is, a normal heartbeat per minute is determined depending on the period of development of the kid. The heart of the embryo responds to any changes in the world that surrounds it. After all, stress or mother's disease directly affects children. Also, the rate of heart blows per minute varies depending on the period of activity or sleep fetal. On the rhythm of the heart reflects the level of oxygen in the air. However, any violations associated with the impact of such factors are temporary.

Provided that the heart rate is too strong for a long time, the doctor may suspect disorders of the supply of fetus blood, the so-called fetoplacentar insufficiency . As a rule, this state is chronic. Sometimes, when the compensatory features of the child are depleted, too slow heart rate is celebrated. This suggests that the state of the fetus has deteriorated. In such a situation, a decision on emergency delivery is sometimes made. The doctor takes into account what a heartbeat should be at what week, and from when the pathology manifested itself, determines the tactics of treatment.

Determination of the state of the fetus in childbirth

During the birth period, the kid is experiencing very strong loads, lack of oxygen and compression. If everything goes well, then his heart and vessels normally cope with such loads. However, sometimes emergency states occur, for example, placenta detachment , pressing cord Which need fast medical care. That is why during childbirth, the doctor determines how many blows is the heart rate after each fight, so as not to miss the development of an acute lack of oxygen.

Ultrasound procedure

The first method to determine if the heart rate is normal or not, it is an ultrasound study. During the ultrasound, along with the heart rate, the doctor assesses the state of the placenta, the size of the fetus.

The tones of the heart are very carefully listening, and its structure is being studied, if the woman has already born children with vasses and hearts. If the mother has suffered infectious diseases during pregnancy, pay special attention to work and the structure of the heart.

If necessary, conduct an ultrasound of the health of the fetus during pregnancy. What time does the ultrasound of the heart of the fetus do, the doctor defines. The most optimal time for the study of Echo kg - 12 weeks. But Echocrite woman can spend both at wishes to make sure that everything is fine with the child.

This method provides for listening to the tones of the heart using a special obstetric stethoscope. True, the answer to the question is whether you can hear the heartbeat in the early periods, negative. The period when you can hear a stethoscope - 18-20 weeks. A doctor with experience can identify a number of indicators with such a device. He listens with what approximately the heart beats the heart, will determine the clarity of the tones and will find the place where they will be listened to the best. The algorithm of listening to the heartbeat of the fetal and definition of the heart rate is simple: this can be done using the stopwatch.

But sometimes to draw a suction with a stethoscope is difficult or at all possible. This is probably if the mother has a very high weight if the placenta is located on the front wall of the uterus (in this case there is a noise of vessels), if there is very few oil-free waters or much.

Cardiotocography (CTG)

This is an informative method, with which you can evaluate the heartset of the fetus. Such a procedure allows in early stages to determine the oxygen starvation of the fetus and to configure this problem in a timely manner.

The CTG apparatus is an ultrasonic sensor that sends and capturing reflected signals from the heart. At the same time, all changes in the rhythm are recorded on the film. Conducting the procedure, the doctor sets not only the main sensor, but also the uterine contraction sensor, with which you can determine the activity of the uterus. In the most modern devices there are sensors of fetal movements, and sometimes there is a special button so that the woman itself can fix movements.

The whole process of research CTG takes about 60 minutes. During this period, in most cases, it is possible to fix the period of sleep and the activity of the fetus. But sometimes there is a need to explore the state of the fetus throughout the day. Then the sensors attached to the stomach leave one day.

Analysis of the heart rate is carried out taking into account the period of pregnancy, which produced a study. For the first time KTG is held at 32 weeks. If you spend it before, in 30 weeks or even more early, the results will be non-informative. When 31 weeks passes, the dependence between cardiac activity and motor activity of the fetus is formed.

Most often, the pregnant woman passes this study twice - in 32 weeks and before the very kind. This procedure does not harm or a woman nor the baby, so it can be carried out as many times as needed.

Decipheres CTG specialist tape, compares the results obtained with analyzes and ultrasound data. However, cardiotocography is not the source of the final diagnosis.

What is "good" ktg

"Good" CGT is considered if the indicators are as follows:

Heart rate normally - from 120 to 160 shots per minute;
when the kid moves, the heart rate increases;
the decrease in the heart rate is not or noted very rarely and in small quantities.

The device analyzes these indicators and provides a special PSP index. If the state of the fetus is normal, then this index is not more than one.

However, it is necessary to take into account that on how the child's heart works, the variety of factors affect. And only a specialist can correctly appreciate them.

Why is the "bad" ktg determined?

The most frequent changes to the CTG are determined if notes hypoxia fruit . The increase in the heart rate is characteristic of a state when the fetus lacks oxygen, and the heart is forced to work very intensively.
When a fight or movement occurs, the kid can slow the heartbeat, which is not a normal state.
Long-term changes on the tape are fixed if the umbilical cord is pressed against the fetus head. At the same time, the results look as well as with oxygen starvation, but the baby feels fine at the same time.
If the sensors were attached incorrectly, the results obtained can also be "bad".

In case of detection hypoxia When listening to the palpitations of the fetus, the doctor conducts additional research to confirm or refute the diagnosis. If hypoxia is confirmed, treatment is carried out, or the doctor makes a decision on an emergency delivery.

Echocardiography

Apply echocardiography in suspected pvs of heart The fetus on the 18-28 week of pregnancy. With this method, you can define the features of the structure of the heart and blood flow. This procedure is carried out in the following cases:

the future mother has children who have diagnosed heart defects;
during pregnancy, infectious diseases were transferred, especially in the first weeks;
mother has congenital heart defects;
future mother more than 38 years;
the woman is diagnosed;
there is a delay in the intrauterine development of the fetus;
the fetus revealed malformations in other organs, and there is a possibility of developing congenital heart defects.

This method is used both as a two-dimensional ultrasound, and using other modes of the scanner (doppler mode, one-dimensional ultrasound. With this combination, the techniques appear to carefully examine the structure of the heart, the characteristics of the blood flow.

Is it possible to determine the heart of the child on the heartbeat?

Many women at a certain period of pregnancy are actively worried about how to determine the sex of the child in the heart of the fetus. After all, among pregnant women and even among some medical workers, "walks the legend", which such a definition is possible, as well as the assumption that determine who will be born - a boy or a girl - the fetus size can help.

It is believed that girls have a heart beats more often, and at 13 weeks or later, they have up to 160 times per minute. According to this "Believe", the boys heartbeat is 135-150 shots. But those who actively ask doctors questions: "How to find out the floor of the child in the heartbeat in 12 weeks" or "From what date it is possible," you need to consider that this method is not scientifically justified. Although there is an opinion that this method is relevant only to 20 weeks.

The question of how many weeks you can determine the sex of the child in this way, is not relevant in principle, and the frequency of heartbeat is not a decisive indicator. After all, it is possible to determine the boy or a girl, in frequency, perhaps with an accuracy of 50%.

True, there is an opinion that in this case it is important that the fetal of the heartbeat. Some "experts" argue that the boys have more rhythmic, and girls are more chaotic.

There is another sign: the boys rhythm the heart coincides with the mother's rhythm, there are no girls. But all these methods have nothing to do with medicine. After all, the heart rate displays the ability of the fetus to overcome the lack of oxygen, and not sexuality. Therefore, moms that begin to "guess" the floor immediately, when the heart begins to beat the embryo, it is better to make a high-quality ultrasound from a good specialist who will help learn the gender with high accuracy.

Is it possible to hear the phonenendoscope heart abbreviations? Those who are interested in how to listen to heartbeat at home can apply several methods. You can hear the sounds of this pleasant for your parents using a stethoscope, a portable device - fetal doppler and, finally, simply applying the ear to the tummy.

Like at home listen heartbeat, it will be discussed below. After all, for this there is no need to attend women's advice. If the future mother and her surroundings have experience, the heart can be heard before. After all, a more experienced woman earlier notices the movement of the fetus at the second pregnancy. The heart rate, however, must be controlled by a doctor.

With stethoscope

You can listen to heart with the help of the most ordinary obstetric stethoscope. It is necessary to purchase an obstetric tube and take advantage of whose help. Of course, the fetus at 12 weeks of pregnancy at home will not be able to listen. If this person has no experience, then earlier than in 25 weeks, nothing will succeed. But if the fetus is listening to 30 weeks, then hear the blows are much easier. You just need to practice slightly and "Call". At the same time, it is necessary to clearly distinguish what it is - the pulse, the peristalsis of pregnant, the movements of the fetus, or all its heartbeat.

Using fetal doppler

If you wish, you can buy a special device - fetal doppler. This is a portable ultrasonic detector, which works as a regular CTG apparatus, but the image is not fixed on the film. Sometimes the headphones are also included so that you can clearly hear sounds. With the help of Doppler, you can hear the sounds of the heart, starting from 8 weeks. However, it is better to start using this device a little later. It is important that the study itself does not last longer than ten minutes.

As the advantages of this device, it should be noted the ability to listen to heartbeat in the early stages, as well as the ease of use and the possibility of a woman to do this without help.

The minuses of the application of Doppler are its big value, restrictions on application. In addition, you should not use this device without measure.

Applying to the stomach ear

Sometimes you can hear the heart, just putting your ear to the tummy. This is possible in recent weeks of the fetus. However, it is possible to get a positive result only if the future mother does not have too much fat layer.

Listening to the heart is needed in a certain place of the abdomen, depending on how the kid is located. If it is down the head, then listening to the heartbeat you need below the female navel. If the child's head is above, then listening to the tones preferably above the mummy. With multiple pregnancy, each fetal heartbeat is heard in different places.

conclusions

Thus, the level of CSS is a very important indicator of the development of the child. Controlled by a doctor during pregnancy. Future mothers should know that heavy heart diseases happen very rarely, and in most cases children are born healthy. But, nevertheless, it is important to regularly undergo all research, control the heartbeat. The rate of blows per minute in women and the child is important indicators, and the doctor takes into account. But the very future mother must be very careful to relate to their own health and "listen" to the baby.

Neither the elderly, nor smart medical professionals understand the aspirations of young families to plan a son or daughter or learn half a child in heartbeat as soon as possible. This is justified except for the danger of transmitting the hereditary disease to children of a certain sexuality. But such cases are extremely rare.

Without going into the reasons for increased interest in determining the sex of the child in the heartbeat at 12 weeks or a little later, we will tell you what they say doctors. Perhaps the opinion of specialists does not coincide with your information on how to determine the sex of the child on heartbeat, but to whom to trust, if not professionals? Let's reckon with the fact that in the courtyard of the XXI century and believe grandmother's fairy tales is simply notolate.

Studying the rate of heart rate first at the embryo, and then the fetus, pay attention to the fact that the reservations on the floor or the dependence of the heart rate from the sexuality is not detected anywhere.

There are boundaries of the maximum permissible lower and upper values \u200b\u200bof the pulse to determine the pathologies of perinatal development:

intrauterine bradycardia - heart rate less than 110 wt / minute;
tachycardia - heart rate from 180 beats per minute and more often.

There are such data as CSS Fetal for weeks in the table. The sex of the child in this data is also not considered. Explanation of this is very simple.

The heart rate is an individual and non-permanent indicator depending on many reasons, including mother health and congenital fruit pathology.

Therefore, someone from future babies of heart rate can be 80-85 beats per minute, and someone has 150-170.

By changing the parameters of the heart rate, the doctor is able to assume the presence of intrauterine diseases of the fetus, but it is impossible to determine the sex of the child by heartbeat.

When does the fetus begin to beat the heart?

Questions like "Is it possible to determine the sex of the child in heartbeat" arise due to the ordinary lightness and the lack of an idea of \u200b\u200bthe physiology of intrauterine development. But it is quite corrected. If you sincerely want to give birth to a healthy child, you will definitely find time to read about the peculiarities of the course of pregnancy, about when the mechanism of work is launched barely formed the heart and is it possible to learn the floor of the child on heartbeat.

The Pulse Pulse Parameters are regularly measured in women's consultation in the framework of pregnancy. This is not done in order to learn the floor of the child on heartbeat, but to track the life of the fetus and timely detection of problems with its health. This is especially important in women from a risk group on cardiovascular and other pathologies (with impaired heart work, hypertension, etc.).

Reliable definition of the floor of the future child - it's not about simple

In obstetrics, the beginning of the abbreviations of the myocardium of the embryo is the 3rd week from conception. But hear it at this time, and even more so determining the gender of a child in the heartbeat in 12-14 weeks or any other time - it is impossible.

Listening to the Pulse Fetal becomes possible only by the beginning of the 6th week of pregnancy (the so-called obstetric, which is calculated from the date of the last menstruation) during the procedure. During this period, the toddler pulse must correspond to the mother's pulse (normal value - 83 +/- 3 beats / minute). Is it possible to determine the sex of the child on the heart of the fetus? It is impossible, but it is possible to calculate its gestational age, knowing that the heart rate is increased every 24 hours by 3 strikes with optimal development.

Gestational age is a complete number of pregnancy weeks from the beginning of the last menstruation, which makes it possible to calculate and more accurate birth time.

Table CSS Fetal for weeks

As follows from the above, the pulse rate of the fetus is steadily changing, which is associated with its intensive growth inside the womb. In the continuation of the whole period of the baby tooling, this figure is periodically measured in women's consultation and compared with optimal indicators, the guidelines for which are listed below.

Obstetric period of pregnancy (full weeks)	Heart rate standards (beats per minute)
6	104-127
7	127-149
8	149-173
9	154-194
10	160-178
11	154-176
12	150-174
13	147-171
14	146-168
20	140-170

Many sources assure that on the heartbeat, you can define the child's gender, considering that there are children of children of different sexes in such tables. They are based on the fact that boys allegedly a rarely pulse, and the paired numbers above are taken as the basis.

But these numbers are only bands - within any numbers there may be a couple meters heart rate. Such a heartbeat is also the boys, and at the girls, the sex of the child in heartbeat or on which otherwise it is impossible to determine.

The infant pulse parameters in the perinatal period correlate (interrelated) with many factors:

mother hormonal background;
individual features of myocardial and conductivity innervation;
the activity of the movement of the fetus;
the number of hemoglobin in the child's blood and mother;
the state of wakefulness or sleep baby in the study;
possible perinatal pathologies - reserves-conflict, bleeding, heavy gestosis, hypoxia of the fetus.

Therefore, all questions on the topic - how to determine the sex of the child on heartbeat in 12 weeks or 20 is untenable.

How to find out - boy or girl - on heartbeat?

In order to finally dispel the myth about the existence of such a technique, how to determine the floor of the future child on heartbeat, even a small study with a group of women awaiting a child.

Researchers tried to determine the child's sexual belonging of 20 weeks before, but the results showed that the prognostic value of this technique was only 50%. What does this figure mean? The same is that the statement of fabulous characters: "One of two - or the patient is alive, or he is no longer breathing." So a positive answer to the question - is it possible to determine the sex of the child on the heart rate - can not.

Test the technique for yourself

The best way out is to wait for a period not by heartbeat at 15 weeks, but on ultrasound. But if it does not wait like that, you can independently check - how to determine the sexuality of the child in the heartset frequency. To do this, go back to the heart rate table for weeks.

Of course, this method cannot be treated seriously, but as an additional entertainment during pregnancy, you can try. In the end, you will not lose anything if the ultrasound coincides with your forecasts or, on the contrary, will show another result.

So, gives us every week in two CSS values \u200b\u200b- the minimum allowable and maximum allowable. Supporters of the method are confident that girls have a heart fighting faster (ah, how they can't wait to appear on the white light!).

Let's define what values \u200b\u200bin our table "can be considered to be girls and what boys. To do this, you have to remember the arithmetic.

When counting, how to learn the floor of the child on the heart of the fetus of 12 weeks, find the TSS values \u200b\u200bin the table for the 12th week: 150-174 wt / minute.
Now consider the difference between large and smaller values \u200b\u200b- 24 beats per minute.
Divide the difference in half - get 12.
Now add 12 to the minimum pulse indicator: 150 + 12 \u003d 162 impact.

So you can listen to the palpulation of the fetus

Well, here, we found the maximum pulse value, which is inherent in future men at the 12th week - no more than 162 shots. All the readings of the heart rate above this value will mean that there is a future lady in your lap (do not forget, this technique is not scientifically confirmed).

Exactly such calculations for each subsequent period. We will analyze another week for one more week.

To calculate how to determine - the future child is a boy or a girl - on the heartbeat at 13 weeks, find the heads of the heart rate for the 13th week, it will be 147-171 shots.
Take away from 171 (more norm) 147 (less value), get 24 again.
Divide 24 in half \u003d 12, and add this number to the minimum value of the norm: 147 + 12 \u003d 159.

In this case, it turns out that if the CSS of the fetus is above 159 shots per minute, then you will have a girl, and if less than 159 shots, it means there will be a boy.

Congratulations, now you know exactly how to determine the sexual personality of a child in the heartbeat of the fetus according to the method of unknown origin.

It's amazing, but, regardless of the diversity of medical articles on the basis of the definition of gender, giving a qualified response about the gender of the baby, many parents still seek the area and embark on doctors.

The most popular of them:

how to learn the floor of the child in the heartbeat at 13 weeks (the sooner, the better!);
how to determine the sex of the child in the heartbeat in 20 weeks (for some reason this period is considered the most suitable for counting the floor on heartbeat).

There are such young parents who are trying to calculate the sexuality of the child. For a physician - a little strange wording, but it is enough to see-read the so-called "Mama Forums" to make sure how the question is popular how to calculate the sex of the child to update the blood of parents.
