What can tell a baby's heartbeat in the womb?


When the heart begins to beat in the fetus? Echocardiography, CTG and ultrasound - methods of investigation of the fetal heart. What does the rhythm, character and tone baby's heartbeat in the womb

Every pregnant woman wants to quickly learn floor the unborn child. For this purpose the so-called traditional methods. Among them there is also a way to determine the sex of the baby in his heartbeat.

What can tell a baby's heartbeat in the womb?First, consider that the number of different sexesbpm significantly different. Boys indices below 140, and the girls - above. However, the official medicine in this regard does not say anything, so do not trust this method, the more so that the heartbeat of the fetus varies depending upon the week of pregnancy.

Second, pay attention to the nature ofheart rate. It is believed that the boys measured rhythm, and the girls - chaotic and more agitated. But there is a perception that boys heart beats louder and coincides with the pulse of the mother, and the girls - on the contrary.

It has the value and location of the fetus. If the heartbeat is heard on the left - the boy on the right - a girl.

In practice, folk diagnosis coincides with the actual results in only half of cases. In addition, the frequency of the heartbeat affects many more factors, which we present below.

When you start an audible heartbeat in the fetus

After about 20-25 days from the moment of conceptionshaped heart. During the transvaginal ultrasound at 5-6 weeks, you can see the first cutting motion. Average transabdominal ultrasound shows the cuts only for 6-7 weeks.

In the first trimester the baby is constantly heartbeatchanges. For example, after the start pulsation rate ranges from 110 to 130 beats per minute. Such a heart rate of the fetus is observed up to 8 weeks of pregnancy. It then increased to 170-190. Since the heart rate of 11-12 weeks is slightly reduced and is 140-160. Such indicators will hold themselves to delivery.

In the initial stages of pregnancy data jumps are quite normal and suggests establishing the functions of the nervous system responsible for the activity of internal organs.

Heart rate is an importantan indicator which indicates the viability of the child. For example, if the rhythm becomes more rare drops to 85-100 beats, or vice versa, faster, rising to 200, it indicates the presence of pathology. In such situations require immediate diagnosis of the causes of the violation.

When the embryo has reached the size of 8 mm, but heartrate is not observed, the medicine, this is called missed abortion. To confirm the diagnosis, conduct another ultrasound after 5-7 days.

So expectant mothers who want to identifypossible floor for fetal heartbeat should be based on the above data. With regard to people's methods, they should be guided by the results only after 21 weeks of pregnancy, when the rate drops will no longer be observed.


Echocardiography is a subspecies of the ultrasound. This method is used for the integrated study of the heart in the fetus. The apparatus includes three scanners, each of which operates in a particular mode (one-dimensional, two-dimensional, Doppler). Carrying echocardiography procedure allows us to consider whether to order the structure of the cardiovascular system or detect violations.

When pregnancy is equal to 28 weeks,This study is not carried out as at a later date to obtain accurate results is difficult due to the decrease of amniotic fluid and an increase in the size of the child.


What can tell a baby's heartbeat in the womb?To determine the sex, the woman can hearheart using a special device - obstetric stethoscope. However, it can only use any of the family members, rather than the pregnancy itself. Stethoscope is a tube with a wide funnel. This aspect is applied to the abdomen and the other listen.

Auscultation is performed at each visitwatching the gynecologist. This method of fetal heart auscultated at 21 weeks of pregnancy and to the birth process. As the development of the child in the womb of heart sounds become more distinct.

It is the most simple and accessible method thatyou can hear a heartbeat at home. However, the difficulty lies in the fact that there are also other sounds, such as bowel sounds that interfere heard heartbeat.

An experienced doctor listening to the heartbeat, draws attention to the following parameters:

  • The above bowel sounds. They are characterized by irregular, transfusions and gurgling;
  • Blowing noises arising from the reduction of the aorta and the uterine vessels (the same as the pulse of the pregnant woman);
  • Determine the best listening point. Its position depends on the location of the fetus in the uterus. For example, if the baby is head down, listen to the best below the navel, with cross previa - on a level with the navel, at the breech - above. However, multiple pregnancies tones can clearly hear anywhere applying a stethoscope;
  • Rhythm. The heartbeat of the fetus during pregnancy should be rhythmic (blows at regular intervals). Arrhythmia tones suggests congenital heart defects or fetal oxygen starvation (hypoxia);
  • Character heart rate. Clearly audible tones indicate normal pregnancy, the deaf - a hypoxia. But in the latter case, the cause could serve as the placenta is located on the front wall of the uterus, multi- or oligohydramnios, obesity, pregnant, multiple pregnancy, and increased activity of the baby.


In late pregnancy (around 32 weeks), ifthere is a need, use the method of CTG or KGT. Special sensors is attached to the abdomen of pregnant and leave for 1 hour. Thus, record the baby's heart and uterine contractions. As a result, the physician can evaluate the heart rate, as well as to determine the change of rhythm in response to a fight.

KGT necessarily to be held in the following cases:

  • Multi- or oligohydramnios;
  • Stunting fetus;
  • Violation of arterial blood flow;
  • Premature aging of the placenta;
  • Changes in heart rate, detected during auscultation;
  • Severe preeclampsia;
  • The scar tissue in the uterus;
  • Temperature pregnant over 38;
  • Chronic diseases, such as hypertension, diabetes;
  • Evoke delivery or stimulation with a weak labor;
  • The birth in preterm or post-term pregnancy.

KGT can not only evaluate the heart rate (the rate -120-160), but the variability rate (permissible fluctuations - 5-25 beats per minute), as well as changes in the frequency of contractions or fetal movements. In addition, this method allows us to detect the acceleration of the heart rate or, on the contrary, the fall of pace.

For example, increased during labor isa positive sign and a decrease - on the contrary. The significant weakening of rhythm manifests itself as a result of fruit and placental insufficiency or oxygen starvation, but it is the norm breech fetus. Very poor indicator has a reduction rate of up to 70 beats per minute.

How to hear the fetal heartbeat at home

What can tell a baby's heartbeat in the womb?Mom, as well as all members of the family,can hear the beating heart baby in the womb, being at home. In so doing, it will help a special device - Fetal Doppler. This compact and easy-to-use device that can even carry. With it, a woman can independently monitor the health of the baby since 12 weeks of pregnancy.

However, it should be borne in mind that the heartbeat of the fetuschanged weekly. It also helps to eliminate anxiety and relieve stress, if deadlines are not observed external signs of fetal life activity, ie tremors.

It is worth noting that both the devices are safeboth mother and child. So if you really want to listen to the beating heart of the child and possibly determine its sex in this parameter, these devices fit perfectly.

However, the best option is the US, although this procedure also can not give 100% results about the sex of the child. Light your labor and health to you and your crumbs!
