B ultrasound showed no fetal heart rate

During the B-ultrasound examination, if no fetal heartbeat is found, don't worry too much. Generally, the fetal heartbeat will appear around 7 weeks of pregnancy, but the physical constitution of pregnant women is different, and the appearance of the fetal heartbeat may be a problem of early or late. At this time, you can go to the hospital for a formal examination. It depends on some specific circumstances. If the symptom of no fetal heartbeat suddenly appears in the middle and late stages of pregnancy, it is generally related to fetal hypoxia. Let's take a look at this aspect.

B ultrasound showed no fetal heart rate

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.

Reasons for no fetal heartbeat

The absence of fetal heartbeat means embryonic arrest. There are many reasons for embryonic arrest, including genetic factors, infection, exposure to radioactive substances, toxic chemicals, taking drugs that are contraindicated during pregnancy, high temperature, excessive stimulation, etc. In most cases, early embryonic development arrest or miscarriage may be due to problems with the chromosomes themselves.
