No fetal heartbeat on ultrasound

We all know that to determine whether the fetus is developing normally, it is necessary to check the fetal heart rate and heart rate through B-ultrasound. If the fetal heart rate is not seen during the B-ultrasound examination, it may be due to fetal malformation or stillbirth. At this time, the fetus cannot be retained and needs to be expelled through abortion. Generally, the fetus can be detected around 7 weeks of pregnancy.

What's going on when there's no fetal heartbeat?

If you can't hear the fetal heartbeat, does it mean that the fetus is not developing well? The fetal heartbeat usually appears around 7 weeks of pregnancy. If you find that there is no fetal heartbeat in the early pregnancy, you should calm down, go to another hospital, or wait another week or two before going for a check-up. If there is still no fetal heartbeat, it may be embryonic arrest. There are many reasons that may lead to fetal growth retardation, including exposure to toxic substances, radiation or large amounts of electromagnetic radiation, taking medications that affect fetal development, smoking or alcoholism, etc. It is recommended to find out the cause and then treat it symptomatically.

The sudden absence of fetal heartbeat in the middle and late stages of pregnancy may be caused by fetal hypoxia, such as umbilical cord lesions: umbilical cord torsion, umbilical cord prolapse, etc.; fetal factors: malformations, intrauterine growth retardation, infection, multiple births, etc.; maternal lesions: post-term pregnancy, pregnancy-induced hypertension, cardiovascular disease, toxic shock, etc.; placental factors: placental abruption, placenta previa, etc. All of the above reasons will lead to insufficient oxygen supply to the placenta, causing the fetus to die from lack of oxygen. It is recommended that pregnant women go to the hospital for examination and receive appropriate treatment immediately once they find the disease.

What to do if there is no fetal heartbeat

Generally, the fetal heartbeat can be seen from the B-ultrasound after 7 weeks of pregnancy. If the B-ultrasound examination finds no fetal heartbeat after 8 weeks of pregnancy, the expectant mother does not need to be too nervous and can continue to observe. If there is still no fetal heartbeat after another one or two weeks, it is considered that the fetus is not developing well. It is not a reaction to miscarriage, but it cannot grow into a healthy baby, so abortion is the only choice. If there is no physiological problem, it will not affect pregnancy again.

If there is no fetal heartbeat during the first pregnancy, before trying to get pregnant again, in addition to checking antibodies on both parties to rule out immune factors, bacterial culture should be performed to rule out infection factors if necessary; and chromosome examination of both parties should be performed to rule out genetic and chromosomal causes if necessary. If you get pregnant again, you will need to carry out systematic fetal preservation.
