Causes of absent heart beats

When some pregnant women are examined, doctors will tell them that the fetus has no heart beat. In fact, the absence of cardiac tube pulsation means that the fetus has no fetal heartbeat. Generally in this situation, the fetus will not develop normally, so abortion is required after it is discovered. So do pregnant mothers know the reason why there is no cardiac pulsation? Let me introduce it to you below.

The doctor said that the fetus had no cardiac tube beating, which means that the fetus had no fetal heart.

The development of the fetal heart rate generally starts from the first day of the last menstrual period and appears between 38 and 70 days of pregnancy. The time when the fetal heart rate appears will be different for each pregnant woman. If there is no fetal heartbeat at this time, either the time has not come yet or the embryo is not alive.

The first situation is easy to understand, but there are many reasons for the second situation:

① Chromosome reasons: One of the spouses has a chromosome problem, which causes the embryo to fail to develop normally and stop developing;

②Survival of the fittest: The combination of sperm and egg itself is a competition of survival of the fittest. It is possible that the seed itself cannot develop due to quality problems;

③ Luteal insufficiency: Some women may be born with luteal insufficiency, and the ovaries cannot secrete enough progesterone, resulting in fetal arrest and cessation of embryonic development, and naturally no fetal heartbeat;

④ Pregnant women have antibodies: Pregnant women have certain antibodies that resist the development of the fetus and can also cause the embryo to stop developing;

⑤Affected by the environment: After pregnancy, if pregnant women are frequently exposed to chemicals or work in places with strong radiation for a long time, the embryo will not be able to develop;

The above reasons are the most common causes of fetal growth retardation. If fetal growth retardation occurs, you must be sure to find out the truth. If you don’t, there is a high possibility that the next pregnancy will cause fetal growth retardation due to the same reasons as last time.

If there is no fetal heartbeat after a certain period of time, it is necessary to deal with it and prepare for pregnancy at least half a year later. It is recommended that the couple have a pregnancy test in the first three months of pregnancy to ensure the greatest possible degree of a healthy baby.
