The clinical significance of fetal heart monitoring includes: first, fetal heart monitoring can determine whether the fetus has hypoxia, if the fetal heartbeat is too frequent or the fetal heart rate is slow during fetal heart monitoring, it is directly related to the health of the fetus, under normal circumstances the fetal heart rate is about 110-160 beats/min, if there is an abnormality, it is recommended to conduct ultrasound examination in time to observe whether the umbilical cord is wrapped around the neck or other abnormalities. If there is any abnormality, it is recommended to have an ultrasound examination in time to observe whether there is cord bypass or other abnormalities. Secondly, fetal heart monitoring can help to understand the reserve capacity of the fetus and the condition of the fetus in the uterus, if the fetus is stunted or in intrauterine distress, it can be detected through fetal heart monitoring. It is very important to go to the hospital regularly for fetal heart monitoring in the middle and late stages of pregnancy, and it is best to seek medical attention if abnormalities are found in the fetus during the pregnancy.
