A high fetal heart rate can be caused by factors such as after fetal movement and intrauterine hypoxia. A fetal heart rate between 110-160 beats per minute is normal. If it exceeds 160 beats per minute, you need to be more vigilant. The cause of high fetal heart rate may be physiologic, i.e., after fetal movement, the fetal heart rate may be high, which is normal. At other times, high fetal heart rate may be caused by intrauterine hypoxia, fetal congenital heart disease and other factors. In addition, during pregnancy, it is important to do obstetric checkups on time. Fetal heart rate monitoring can be done to understand the condition of the fetus, and oxygen can be administered to regulate the condition if necessary. Pregnant women can monitor the fetal movement at home and count the number of movements by themselves, and if there are frequent movements, they need to consult a doctor in time.
