How many weeks pregnant do you start fetal heart monitoring?

Normal pregnant women, if there are no complications and complications of pregnancy, start routine fetal heart monitoring from 34 weeks. If there are complications or complications of pregnancy, such as gestational hypertension disease, gestational diabetes, and other systemic complications such as immune system diseases, fetal heart monitoring can be started appropriately in advance, 32 weeks, 30 weeks or even 28 weeks. The standard of fetal heart monitoring is to look at the baseline of fetal heart rate. If the fetal heart rate is between 110 and 160 beats/min, the number of fetal heart rate is normal. At the same time, observe the variation of fetal heart rate baseline and whether there is fetal heart acceleration after fetal movement. If there is effective fetal heart acceleration after fetal movement, it indicates that the fetal heart reserve function is good and the fetus is not in hypoxia state. If fetal heart rate monitoring shows fetal heart rate deceleration, the presence of fetal hypoxia should be considered for further monitoring.
