Analysis of the reasons why there is no fetal heart rate in the second month of pregnancy

summary

A few days ago, my female colleagues and I went to have a physical examination after pregnancy. We were almost two months pregnant, and everything was normal. But my colleagues couldn't find the fetal heart rate, that is to say, they didn't detect the fetal heart rate. This is the first time I've heard about it. I'm very nervous to see my colleagues, and I don't know what to do. After a while, I asked her what to do, and she said that she would review it in two days, but the final result was not known. Anyway, it seems that it is not optimistic. What is the cause of fetal heart failure?

Analysis of the reasons why there is no fetal heart rate in the second month of pregnancy

First, this kind of situation belongs to fetal arrest. There are many reasons leading to fetal arrest, including immune factors, genetic factors, infectious factors, endocrine factors, etc. In general, the first pregnancy is the occurrence of fetal arrest, if you can not find the cause of the disease, then later pregnancy rely on blind fetal protection is unable to keep.

Second, the main reasons for no fetal heart rate: first, the embryo is too small. Second, the first is to stop childbearing. There are four main reasons for embryo suspension: one is reproductive endocrine, the other is estrogen, the other is progesterone, and the other is chorionic gonadotropin. If the mother's endogenous hormone is not enough, it will cause embryo suspension.

Third: at 7 weeks of pregnancy, B-ultrasound can clearly see the fetal bud and fetal heartbeat, and the fetal sac accounts for about 1 / 3 of the uterine cavity. Three months of pregnancy should be able to see the heart tube pulsation, some people may have long menstrual cycle, or gestational sac implantation later, there will be some time error.
