Slow fetal heart rate, that is, when the fetal heart rate is detected, the fetal heart rate is less than 110 beats per minute and lasts for more than 10 minutes, can be called fetal bradycardia, which may be related to the mother’s physical condition or fetal development, and can be further analyzed according to the actual situation to clarify the cause and determine whether intervention is needed. Common causes: 1, the mother’s physical factors: for example, the mother has heart disease, anemia, hypertension, diabetes and other diseases, blood circulation is reduced, so that the fetus lack of oxygen, or the mother takes some drugs, through the placenta act on the fetus, may cause the performance of slow fetal heart; 2, fetal development: such as placenta praevia, placenta abruptio, placental dysfunction, umbilical cord prolapse, twisted and other conditions, or the fetus suffers from congenital Heart disease, abnormal neurodevelopment, hemolytic diseases and other conditions will cause fetal dysplasia, there will also be the performance of slow fetal heartbeat; 3, other: in more than 40 weeks of pregnancy, due to more than the due date, there may be fetal hypoxia, the fetal heartbeat will also be low at this time. Treatment: After pregnancy, pregnant women should have regular maternity checkups, pay close attention to their health, and actively cooperate with the examination after finding slow fetal heartbeat to clarify the cause and determine whether treatment is needed. If the symptoms are mild, you can observe and pay attention to rest and nutritional supplements; if the situation is more serious and the fetal heart rate is persistent or repeated, you need further examination to clarify the condition of the fetus in the uterus, determine whether the pregnancy needs to be terminated, and do a good job of neonatal resuscitation to ensure the safety of the pregnant woman and the fetus.
