What is fetal heart rate monitoring? Fetal heart rate monitoring is a method that uses the fetal heartbeat to monitor the health of the fetus. The fetal heartbeat is its \”symbol of life\” in the mother\’s body. Monitoring the fetal heartbeat can detect the fetal heart rate and detect fetal emergencies in a timely manner. There are two methods of fetal heart rate monitoring: external monitoring and internal monitoring. External monitoring is mainly through external monitoring through sigmoid colon testing, while internal monitoring is through internal monitoring in the vagina or cervix of pregnant women. The status of the fetus in the womb is changing all the time, and the fetal heart rate monitoring results of each baby are different.
