What causes no fetal heartbeat during pregnancy?

Due to various reasons, the fetus will have many different problems in the process of growth and development, so it is easy for the fetus to have abnormalities, which is a matter of greatest concern to all parents. Fetal heartbeat is an important indicator of fetal health, and it is also a must-check during prenatal checkups. What is the reason for the absence of fetal heartbeat during pregnancy? If the pregnant woman is sick or the mother is in poor health, it will also affect the fetal heartbeat. For example, if the thyroid hormone is too high, or if the mother has a cold or fever, the child's heart rate will soar to more than 160 beats/minute.

Congenital heart disease

If the baby in your belly is unfortunately suffering from congenital heart disease, then during the examination, you will find that there is a high probability of long-term bradycardia.

Fetal neural growth and development

At 40 weeks of pregnancy, due to the further development of the baby's central nervous system, the heart rate may be affected and fall below 120 beats/minute. At this time, you should contact a doctor for examination to ensure that there is no possibility of oxygen deficiency.

Fetal intrauterine hypoxia

Generally speaking, most of these abnormal manifestations are caused by fetal intrauterine hypoxia. The more abnormal they are, the more serious the hypoxia is. Therefore, timely medical treatment can effectively prevent the child from suffering more harm.

Pregnant women taking medicine

Due to human reasons or the need to protect the fetus, pregnant mothers will take some medicines, which will also affect the normal heartbeat of the child. For example, "Albuterol" will cause the heart rate to increase, while "Propranolol" will cause the heart rate to slow down.

What are the signs of pregnancy without fetal heartbeat?

1. Did you have bleeding or abdominal pain during pregnancy? If you experience bleeding or abdominal pain during pregnancy, you should pay close attention. Bleeding or abdominal pain during pregnancy is definitely abnormal. If this happens, you should go to the hospital to find out the cause.

2. Take a blood test to check hcg, which is human chorionic gonadotropin. The comparison can be done every few days. In early pregnancy, hcg levels double. If HCG does not increase but decreases, or grows slowly, it is abnormal. HCG is the most direct data to reflect whether the test tube embryo is normal.

3. If the menstrual cycle is relatively long, it may be that the fertilized egg implants late. If the menstrual cycle is relatively regular, the embryo can be seen in more than 6 weeks, and the fetal heartbeat can be seen in about 8 weeks. As late as 10-11 weeks, the fetal heartbeat should be seen. If there is no fetal heartbeat after more than 10 weeks, the possibility of fetal arrest is relatively large. If there is basically no fetal heartbeat for more than two months, don't wait. No matter the length of the cycle, as long as pregnancy is detected, the embryo has implanted. If the embryo has been implanted for so many years and there is still no fetal heartbeat, you need to give up. If the test tube embryo has stopped developing, and there is no miscarriage due to the influence of estrogen, you have to have an abortion. Keeping the embryo in the body is very bad for the body.
