I wonder when the fetal heart is fully developed What are the signs of a bad fetal heart?

If you want to judge whether the fetal heart is developing well, you can make a preliminary judgment by listening to the fetal heart rate at 12 weeks of pregnancy. This can also be done with a Doppler fetal heart rate monitor or with an earpiece, which can be monitored by fetal heart rate monitoring. Under normal circumstances, the fetal heart rate is maintained between 120 and 160 beats per minute, if the fetal heart rate is too slow, or too fast, beyond this range, it is considered abnormal.

If there is abnormality, it should be checked and determined in time, and a four-dimensional examination should be done between 22-26 weeks of pregnancy, which can accurately judge the status of fetal heart development, if there is a ventricular septal defect, or heart valve insufficiency, it can be accurately judged by doing a four-dimensional examination. If the condition is more serious, the baby can be avoided from being born and labor can be induced in time. If the problem is not large, surgery can be done after the baby is born**.

The fetus has a bad heart, the pregnant woman has no symptoms, and the fetus cannot be judged based on the conscious symptoms of the pregnant woman. If the fetal heart is found to be bad, it is mainly the usual examination, fertility examination, ultrasound of the fetal system, especially around 32 weeks of pregnancy, which needs to be examined by the ultrasound of the fetal heart to determine. If you find that the fetal heart rate is bad.

It also depends on the degree of congenital heart disease, if it is a severe congenital heart disease, such as tetralogy of Fallot, the pregnancy needs to be terminated. Mild heart disease, such as tricuspid regurgitation, can be surgically corrected after the baby is born.

Signs of a bad heart in your fetus.

1. If the fetal heart is not good, when listening to the fetal heart rate or doing fetal heart rate monitoring, it will be found that the fetal heartbeat is too fast or slow, and the rhythm is irregular.

2. Color Doppler ultrasonography of the fetal heart may find structural abnormalities of the fetal heart, such as ventricular septal defect or ventricular septal defect, single ventricle, etc.

3. Under normal circumstances, the fetus has heart disease, and the pregnant woman does not have any abnormal sensation, which can be found only through various examinations.

Causes of a bad heart in the fetus.

1. Congenital heart disease is the most common type of congenital malformation, which is an abnormal anatomical structure caused by the formation disorder or abnormal development of the heart and large blood vessels during embryonic development, or the failure to close the channel that should be automatically closed after birth.

2. There are many congenital heart diseases, and it is generally believed that the first trimester of pregnancy, that is, 5 to 8 weeks of pregnancy, is the most important moment for fetal heart development.

3. The causes of poor fetal heart rate include genetic factors and environmental factors, including women taking drugs during pregnancy, infection with viruses, environmental pollution, radiation, etc.

When the fetus's heart is developing, the pregnant woman will not feel anything. It can only be seen by technical means, so it is important to emphasize that fetal heart ultrasound is performed during pregnancy, and fetal heart ultrasound is non-invasive.

The fetal heart is generally fully developed around 26 weeks of pregnancy, and if the fetus has symptoms such as heart failure and developmental delay, it should be considered that the fetal heart has a problem.

It may be found that the fetal heart beats too fast or too slowly, and the rhythm is irregular.

Pregnant women hope that they can give birth to a healthy baby during pregnancy, but it is easy to have unpredictable accidents, under the influence of this accident, the baby is prone to dysplasia, the fetal heart is a very important human organ, incomplete heart development will affect the growth of the baby, what is the cause of poor fetal heart development?

1.There are many causes of congenital heart disease, which may be related to the health and nutritional status of the mother during pregnancy.1Viral infections such as rubella, mumps, influenza, etc., which may affect the development of the fetus's heart and large blood vessels, form congenital heart disease or have other malformations at the same time.

2.Endocrine disorders of the mother during pregnancy;

3.Exposure to radiation or other drugs or poisons may also cause cardiovascular malformations in the fetus.

4.The environment, familial and genetic factors of hypoxia in the plateau area may also be the cause of the occurrence.

Other factors: First, a part of the fetal heart stops developing at a lower stage, or due to an axial error in the process of development, such as translocation of large vessels.

Second, maternal diseases often affect fetal development, and if the mother is infected by viruses in the first 3 months of pregnancy, especially rubella virus, children are prone to heart malformations.

Third, the mother takes certain drugs during pregnancy, which can also cause fetal heart malformations.

Fourth, certain genetic factors that can lead to congenital heart disease.

5. The development of a certain part of the fetal heart stops at a lower stage, or due to an error in the axis rotation during development, such as translocation of large vessels.

Sixth, maternal diseases often affect fetal development, and if the mother is infected with viruses in the first 3 months of pregnancy, especially rubella virus, children are prone to heart malformations. Certain medications taken by the mother during pregnancy can also cause heart malformations in the fetus.

7. Certain genetic factors that can lead to congenital heart disease.

Abortion is when the embryo stops growing for some reason in the first trimester. B-ultrasound examination shows fetal bud or fetal morphology in the gestational sac, absence of fetal heartbeat, or withering of the gestational sac. Clinically falls under the category of miscarriage or stillbirth.

There are many causes of abortion. There are five common reasons:

1. Reproductive endocrine problems, the early development of the embryo needs three important hormones, if the mother's own endogenous hormones are insufficient, it will cause the termination of the embryo. This is the focus of traditional tire protection.

2. Uterine problems, mainly the internal environment of the uterus, uterine mediastinum and other problems, can be done BC, hysteroscopy.

3. Chromosomal problems, both husband and wife take blood for examination, which can be simply ruled out.

4. The problem of reproductive immunity is divided into autoimmune type and alloimmune type. The corresponding examination is complicated and generally not understood by doctors.

5. The mother's own blood coagulation problem, hypercoagulation forms a pre-thrombotic state, which affects the blood flow of the uterine artery, resulting in insufficient blood supply to the placenta, and will also cause the baby to be bad.

Disease analysis: The fetus generally begins to have germ and primitive heart tube pulsation at about 7 weeks, and then gradually goes through developmental processes such as growth, twisting, rotational separation, etc., until the end of the 8th week of pregnancy, the normal cardiac effect will form a structure, and the relationship between the heart and the artery can be shown at the 10th week.

Suggestions: During pregnancy, we should pay more attention to rest, avoid overwork, relax our mind, go to the hospital for prenatal check-ups regularly, closely observe whether there are abnormal changes in the body, and add some qi and blood supplements, protein, vitamins and nutrition, meat and vegetarian nutrition, and pay attention to the diversification of diet.
