A common cause of high fetal heart rate is intrauterine hypoxia. Fetal monitoring is not only about fetal heart rate, if the fetal heart rate is fast in the past, and the other issues such as fetal baseline, fetal monitoring response, no acceleration and deceleration are normal, then there is no need to worry, pay attention to the fetal movement, and have regular checkups. If the fetal heart rate is very fast on fetal cardiac monitoring and frequent late decelerations occur, it is usually considered that the fetus is in intrauterine distress, then it is necessary to administer oxygen to help the fetus to be resuscitated, and continue to monitor the fetal monitoring. If there is no improvement, then emergency cesarean section is needed. In the clinic, if the mother has fever, the fetal heart rate will also be fast, and the mother needs to be helped to cool down. Therefore, in the clinic, if the fetal heart rate is fast, you need to consult a doctor in time, under the guidance of the doctor to identify the specific causes of the disease, and give targeted treatment.
