How to calculate the fetal heartbeat at home. Causes of heart rate disorders. How and where to apply devices to the stomach

19.06.2019

The first heartbeat of the fetus can be heard at the moment when the germ starts his movement for the first time. Fetal heartbeat at home can be heard using a simple stethoscope. To do this, it is necessary to apply a stethoscope tube to the bottom of the abdomen on the right or left. This will allow you to hear a quiet heartbeat of your baby. This method allows you to very easily listen to the beat of your child's heart without special equipment and appliances. Normally, the child's heart must be twice as fast compared to the heart of the mother.

Heartbeat without apparatus

In some cases, you can determine the baby's heartbeat even without using additional devices, for this you only need to attach your ear to the stomach. True, the presence of such a sound does not mean the norm of the child's heartbeat. According to available information, the intensity of the biotivation of the health of the fetus in the abdomen of the mother can give clear projections to its development soon. With the help of such an indicator, you can identify the presence of the neurological progression of the child at this age when it starts to move.

Measuring heartbeat should be carried out on different periods of pregnancy, and their intensity on the period of 20 to 38 weeks should not be less than 6 times. It also became known that at the 28th week of pregnancy, the variation of the child's heartbeat is considered a precursor of the usual development of the fetus and a child up to two years of life without any significant deviations. At the same time, research in the field of heartbeat frequency on the 6th and 12th week of pregnancy is not able to give such results. In addition, such a survey can be a guarantee of advanced speech indicators at the kid by 30 months after birth. These all data were marked by scientists.

It also happens that the beating of the heart of the embryo can be sick even in 12 weeks of pregnancy, but most often this fact is explained by the fact that the ultrasound apparatus has low quality, and actually there is a heartbeat. For this reason, the doctor often sends a pregnant woman to conduct a re-examination, because the question of how long the heartbeat can be heard, quite relative. However, no matter how it is, you should not panic ahead of time, but simply pass a re-comprehensive examination.

The frequency of heart rhythms of the child, which develops in the womb is an important indicator. It allows you to learn about the state of his health, and with high accuracy to assess its degree of development. Fetal heartbeat on weeks counts an experienced doctor using a special medical equipment. Already in the third trimester, the future mother can independently listen and calculate the frequency of heart rhythms of his baby.

In contact with

Time of formation

As a rule, the palpulation of the fetus appears after 30 days after successful implantation. The fact is that from all organs the heart is formed one of the first. Its formation occurs from 21 days after conception. On the 3-4 week, the heart muscle is a small hollow tube, which, however, is already able to reduce. A full-fledged four-chamber organ it becomes at the 8th week of pregnancy.

To hear the heartbeat, a woman needs to visit the ultrasound doctor.

Note! It is possible to determine the cardiac rhythm frequency in the early periods only using a transvaginal sensor.

Starting from the third month of pregnancy, research is already possible abdominal.

The number of abbreviations with normal tooling the child should be Not less than 80-100 And no more than 200 per minute.

The time when the heart begins to beat the fetus, as a rule, all women have the same.

However, if it was not possible to hear it on the first, but a fruit egg in the uterus is visualized, it is not necessary to get upset prematurely.

The fact is that conception time can be installed incorrectly and the heart muscle has not yet had time Fully forms. The doctor will definitely prescribe a re-study after 7-14 days. When the fetal heartbeat is heard on the ultrasound, you can confidently argue that pregnancy it is not frozen.

It is worth noting that on the first examination at the ultrasound, the doctor may not hear what the heartbeat in the embryo, if the study is produced on the old apparatus. Therefore, the woman is best to contact a good clinic with high-quality medical equipment and experienced specialists.

With what heard heartbeat? As a rule, in the middle of the second month after implantation, the level of chorionic gonadotropin reaches a mark of 7200 me / l. With this indicator, you can already see the fruit egg in the uterine cavity, and distinguish between the beat of the still not formed the heart muscle. Knowing, with what hgch heard heartbeat, you can correctly pick up the day of the doctor visiting, which with the help of modern equipment confirm the pregnancy.

Measuring cardiac rhythm It is important to carry out within first trimester. The fact is that it is in the first three months of embryos that congenital vices may occur. As a rule, pathology appears due to the harmful habits of the future mother, taking antibiotics, hereditary predisposition, strong stress and infectious diseases.

To try to exclude the wrong development of the child in a child, recommended plan a conceptionin advance. A few months before pregnancy, you should completely get rid of bad habits, stop the reception of medical drugs that can be toxic to the baby, exclude coffee and tea from your diet, try not to be nervous and not worried about anyone.

Measurement methods

Fetal heart rate is measured using modern hardware methodsto which belong

Ultrasound is one of the most common ways to determine the deadline for pregnancy, the size of the child, the study of the heart muscle and listening to its tones. Listen to the frequency of abbreviations on ultrasound examination can already be for 5-7 obstetse week. When the fetal heartbeat is heard on the ultrasound for the first time, the woman feels true happiness, as now she is sure that the baby develops normally.
Stethoscope is a medical device that can take advantage of not only specialists, but also people without medical education. A stereoscope can be used closer to the third trimester.
Cardiography that allows you to determine whether the heart muscle works correctly. With high accuracy, this method can reveal oxygen starvation, so the doctor has the ability to take the necessary measures in a timely manner. For the first time it is held in the middle of the third trimester . Cardiography can assign before. This is done if other hardware examination methods were given dubious results.
Echocardiography is one of the highly informative methods of ultrasound examination. EchoCg appoint for 18-28 weekIf the doctor has a suspicion of development in the embryo of the pounding of the heart muscle.

Each of the above methods is informative and high-precision. Hardware research methods not only make it possible to calculate the fetal heartbeat on weeks, but also to identify anomalies in a timely manner in the development of the embryo.

Is it possible to feel the beating through the belly

In independence from the period of pregnancy, a woman can't feelfuture heartbeat.

What she takes for heart strikes is only a ripple of her own aorta, which arises as a result of pressure increase in this vessel.

The pressure jump occurs due to serious hormone changes occurring in the female body.

If a woman is feeling through belly Something similar to heartbeat, it is necessary to apply to the gynecologist, who, after a thorough examination, can direct it to a consultation to the experienced cardiologist.

Can I hear the fetal heartbeat yourself at home? It is quite difficult to carry out this without the help of specialized medical equipment. Fortunately, today you can purchase devices that will allow you to hear the heart of the long-awaited and already hot beloved baby in the third trimester.

How can you independently listen

Wanting to listen to the heartbeat of the fetus at home, you should know that on the early term to do it independently impossible.In the first and second trimesters, it can only carry out a specialist using special equipment.

Popular methods, how to listen to the heartset of the fetus at home:

Fetal doppler, which can be used from the second trimester. This ultrasonic detector provides a fairly accurate result. However, the cost of such an instrument is high.
Starting from the third trimester, the future mother can listen to the babe of a baby's heart with a stethoscope. However, in some cases it fails to do. For example, hearing the frequency of impacts can be complicated due to the thick fat layer on the abdomen of the mother or large.

All of the above devices are absolutely harmless to the embryo. However, often the baby feels radiation emanating from the apparatus, and all the time tries to move away from its rays. If a woman feels a child's concern, it is best to postpone the measurement until the baby calms down. Measuring time should not exceed 10 minutes.A longer use of the apparatus causes stress in a child.

Norm

Rhythm frequency directly depends directly from the time to wear the child. Modern doctors were installed heartbeat ratefetal for weeks, which allows you to control the development of the embryo.

Fetal heartbeat for weeks is represented in the following table.

Why is it important to know what a fetal heart rate is on weeks?

The fact is that after seeing deviations in the rhythm frequency of the child's heart, you can warnspontaneous miscarriage and development in the embryo of dangerous illness.

However, with a minor deviation, the diagnosis is usually not put.

Too Fast beating The hearts at the embryo may be due to:

Strong stress that is experiencing a future mother.
Chronic.
Disadvantage of oxygen In the premises, where the future mother often spends their time.
Anemia.

The mandatory point during childbirth is to measure the frequency of heart blows in the child, since during the delivery of the kid is experiencing severe stress and the lack of oxygen. The rate of beating is 140 beats per minute. However, in some cases, this indicator can reach 160.

Important! Controlling the abbreviation frequency, the doctor can determine when the placenta is detachment or notice the reboot of the umbilical.

Fetal Doppler is a modern medical device designed for the purpose of exploitation in the field of gynecology and obstetrics.

This is a fetal heartbeat device that allows real-time monitoring and diagnose the overall condition of the child.

The device is intended for use in hospitals, women's consultations, clinics or hospitals of a specialized profile, as well as for self-use.

A complete description of the fetal doppler is harmful or not, as well as the instruction, how it works and for which the device needs is described further.

This is extremely useful information and a significant aspect for the peace of mind of future mothers who want to keep his hand on the pulse and be aware of the normal development of the baby.

For clarity, it is necessary to understand the difference between the mini-doppler for pregnant women and professional ultrasound (2-4d or ultrasound in principle).

Slight effect on the fruit

The influence of the medical stationary unit is 8 times stronger and higher than that of the portable apparatus for listening to the work of the child's heart using blood flow measurement.

In many countries, including Russian health services or FDA structures in America, restrictions on the impact of ultrasound radiation are established.

The use of mini-doppler to listen to the heartbeat does not require high power and is recognized as safe for mother or fetus.

However, monitoring at home does not cancel visits to the doctor, as well as the passage of planned ultrasound.

Rating devices

Companies for the production of medical devices offer a large range of high-tech portable fetal dopplers economy, medium and premium class.

The choice of a device for measuring the fetal heartbeat depends on the financial capabilities and requests of consumers.

Ultrasound frequencies in both budget models and expensive competitors are almost the same.

The main characteristics of the autonomous apparatus for the hearing of the heart differ in the following criteria:

product dimensions;
dispersion scale;
the possibility of displaying, as well as printing cardiodiagram and histograms;
refractory functioning: 2-4 hours budget series, expensive models for a whole day;
musical accompaniment;
additional applications - Headphone input, Connecting to a computer, Recording Research on CD / DVD, Power Source, Price.

High costs are distinguished complex multifunctional manual devices, fixing the parameters of the vital activity of the mother and child:

calving blood oxygenation;
listening to breathing frequency;
measuring the blood pressure of the fetus;
checking pulse or heart muscle cuts;
reaction (backlight, beep) for critical indicators for examination.

We listen to heartbeat carefully

The popularity of embryonic dopplers is due to the ability to identify the fetal heartbeat in the early stages: from 8-9 to 12, and in some at the 16th week of pregnancy. Depends on the sensitivity of the Doppler.

Instructions for use

The principle of work of home ultrasound is quite simple. Especially burning are the future mothers with difficult pregnancy or previous miscarriages (threat).

Women who resort to the help of such devices are more relaxed, are less susceptible to stress or unrest on the health of the child.

It is possible to independently determine how the baby's heart works in comfortable home in pregnant women since 8-12 weeks.

What is listening, as well as how to use Doppler is described in detail in the attached poster.

Beautiful design - not the most important thing

Instructions for use Pocket Fetal Doppler:

Open the box, check the availability of additional accessories.
Insert batteries or batteries in the power compartment.
Click Start to make sure the product condition.
Abundantly process the touch sensor with good quality gel, without bubbles and inclusions.
Attach the panel to the pubic zone (early) gradually promoting a navel with circular motions to determine the hearing of the rhythm.
The purity of the sound usually comes from the back of the fruit.
Use headphones by setting the desired volume.
The best device for use has the frequency of the Uz-signal from 2.0 MHz.
From what week to check whether the heartbeat depends on the sensitivity of the device.
After use, carefully remove the gel from the sensor with a soft matter, the protests of the alcohol details. Chemicals are prohibited.

On a note! It is best to carry out the procedure with a complete bladder.

Not needed in late terms

How often can fetal doppler depends on your mood and mobility of the nervous system. The device is absolutely safe, but can disturb the crumb.

The best policy is the prudence of the mother. After all, you can record your favorite sounds, and then enjoy at least every minute.

Indications future heartbeat are one of the fundamental characteristics of the normally flowing pregnancy and the viability of the future child. That is why obstetres constantly monitor the heart abbreviations and development of the cardiovascular system of the fetus.

Without the use of high-tech equipment, the first fetal heartbeats can be listened to a stethoscope no earlier than the 18-20 week of pregnancy. At the beginning of pregnancy, estimate the condition of the heart and listen to heart abbreviations became possible only after the invention of ultrasound.

In other cases, muted fetal heartbeat may indicate:

feto-placental insufficiency;
long fetus hypoxia;
multi- or low;
pelvic prevention of the fetus;
the location of the placenta on the front wall of the uterus;
elevated motor activity of the fetus.

Weak heartbeat

Weak fetal heartbeat indicates increasing chronic hypoxia, threatening the life of the fetus. In the early deadlines, the weak palpitations of the fetus can serve as a signal of the threat of pregnancy interrupt, but sometimes such a state is just the result of improper establishment of the period of pregnancy.

Weak heartbeat in II and III trimesters may indicate a long hypoxia of the fetus. It appears after the tachycardia period and is characterized by a sharp decrease in the number of cardiac abbreviations (less than 120 ° C. / minute). In some cases, such a state may be an indication for urgent operational delivery.

Do not listen to the fetal heartbeat

If, with the size of the embryo, 5 mm and the palpitation of the fetus is no longer listening, then the gynecologists are diagnosed with "undeveloping pregnancy". Most cases of undeveloped pregnancy are detected at the deadlines until 12 weeks of pregnancy.

In some cases, the lack of a fetal heartbeat is observed when the fruit egg is detected in the absence of an embryo - such a condition is called an embryonium. It indicates that the death of the embryo occurred on an earlier period, or he did not laugh at all.

In such cases, a woman is prescribed a re-examination of the ultrasound in 5-7 days. In the absence of heartbeat and with a repeated examination, the diagnosis "undeveloped pregnancy (anembosition)" is confirmed; A woman prescribe the scraping of the uterus.

The intrauterine death of the fetus may indicate the lack of palpitations from the fetus on the 18-28 week of pregnancy. In such cases, the obstetrician-gynecologist decides on the conduct of artificial genera or fertilizing operation.

Is it possible to determine the sex of the child on the heart of the fetus?

There are several folk techniques for determining the floor of the child in the heart of the fetus, but doctors refute them.

One of these ways suggests listening to the heart rhythm of the fetus. The boys, according to adherents of such a technique, the heart beats more rhythmically and clearly, and the girls are more chaotic, and the rhythm of heartbeat does not coincide with the maternal.

According to the second similar folk technique, the place of heartbeat may indicate on the gender floor. Listening to the left means the girl will be born, and the right is a boy.

The third folk technique states that the amount of heart abbreviations may indicate the gender of the baby, but the versions of this method are so much that they became very confusing. Some claim that girls have the number of heartbeats should be more than 150, then less than 140 shots in one minute, and the heart in boys beats then more than 160 shots per minute, then about 120. There are also exact terms of such testing.

Despite all the enormality of these methods, they are no more than playing in "guessing". All these methods are fully refuted by scientifically proven facts indicating that the amount of heart abbreviations affects:

gestational age;
the position of the mother's body during listening to the heartbeat;
motor and emotional mothers activity;
the state of health of the future kid and mother.

Medical studies confirm that learn the floor of the future child with 100% accuracy is possible only when conducting a special method, during which an amniotic fluid or a piece of placenta tissue takes.

Can I feel the heartset of the fetus?

Fetal heartbeat, putting a hand to the stomach, a woman cannot on any gestation period, since a stethoscope is needed to listen to heart tones. In some cases, a pregnant woman feels a pulsation in the abdomen or in the lower backs of the back and takes these sensations for the palpitation of the fetus. Such ripple does not reflect the heart abbreviations of the fetus, but indicates an increased pressure in the aorta, which may occur against the background of the hormonal restructuring of the body during pregnancy. Before use, you must consult with a specialist.

The heart of the embryo begins to decline at the end of the third week of embryonic development. Moreover, the first is reduced by the ventricle, and a few later - the atrium of the embryo.

At this stage, these structures are still separated by partitions on the right and left departments, and they function as a whole.

Of course, using modern diagnostic equipment, it is possible to hear the heartset of the fetus from the very moment when the little heart begins to pulsate. With the help of an obstetric stethoscope, you can also hear the heart of your baby, but somewhat later - from 18-20 weeks of pregnancy.

Listen to the sounds of the heart of the fetus - this is a big joy for mom. Auscultation (listening) is also important for assessing the state of a developing body.

What a baby can tell us, will be told a little later. For starters, let's consider the normal figures of the heart rate (heart rate) of the embryo.

What should there be an emergency organism?

The frequency of the heart of the fetus varies depending on the period of pregnancy. Below we give a table for you, in which normal Numbers Numbers are prescribed for specific pregnancy terms.

Having studied this table, you probably noticed some pattern. CSS Fetal gradually increasing, reaching a maximum of 9-10 weeks of pregnancy, and then decreases and fixed at 140-160 shots to the end of the intrauterine development.

Fetal Heart Development

After registration of cardiac activity or auscultation, you can get some other numbers. With what it can be connected? Many factors may be involved here, such as the phase of the fetus activity or the general condition of the mother. However, when a deviation is detected from the norm, first of all it is necessary to exclude the pathology of the mother or child.

Camera Decision

Why are the intrauterine auscultation of the heart?

It is possible to distinguish three main reasons for the need to listen to the heart of the child in the womb.

Now let's return to the main issue - about the possibilities of stethoscopes for the auscultation of the heartbeat of the body, developing intrauterine. We also want to tell you about more complex equipment, which is currently actively used with the above goal.

Methods of registration of cardiac activity of the embryo

Auscultation.
Ultrasound.
Dopplerography.
Cardiography (CTG).

There are different options for registering KTG. Usually, all the procedure takes about an hour. This time is sufficient to register both the phase of activity and the embryo sleep phase.

A variant is possible when the detector is attached to the belly of a pregnant woman for the whole day and then analyze the total picture of the embryo activity.

There is also a portable CTG apparatus, which, by analogy with a portable ultrasound device, a doctor can bring with him to the ward to the patient, take on the departure and so on.

Portable CTG The device is often trying on in modern clinics, because it allows not to "tie" a woman to cumbersome equipment.

In addition, the modern KTG device allows you to register how your kid moves. For this purpose, a separate detector is used, which is fixed on the stomach of the mother.

Moreover, such devices provide for the possibility of changing the position of the detectors of a woman. To do this, there is a special button by pressing which a change in the position of the sensor is ensured, as well as its fixation. Who knows the best mom about where the baby usually "beats" and "knocks"?

However, the CTG method is informative already in late pregnancy. The first such study is carried out only after a 32-week period. After all, it is from this moment that it establishes a clear relationship between the movements of the fetus, as well as the activities of his heart.

As a rule, women undergo this study twice - in 32 weeks, and then immediately before childbirth.

But in the presence of testimony, KTG can be carried out more than once, because the procedure itself is absolutely safe, as well as harmless.

Mom experience about self-listening attempts

Anna K., 25 years: "During the first pregnancy, I really wanted to listen to how my baby's heart works. But all attempts were unsuccessful. There were no reasons for anxiety - because every day I felt like a baby moves and, of course, a doctor was regularly shown. As it turned out later, the reason was that I used the usual stethoscope from the tonometer. Such a device, unfortunately, will not be able to listen to the child's heartbeat. "

Victoria D., 20 years old: "When I was preparing to become my mother, I often wondered about whether you can hear the heart of a child who is in my stomach. After all, doctors constantly use some complicated technique, special methods, to figure out which is not so easy. And sometimes I wanted to hear the heartbeat of my child in the evening, sitting at home on the sofa with her husband. But at our disposal was an ordinary stethoscope and with it, we were able to listen only to intestinal noises. "
