When should a fetal heart monitor belt be used?

Fetal heart monitor belt, also known as a fetal heart rate monitoring belt, is generally used at 36 weeks of pregnancy. The details are as follows:

In the late stages of pregnancy, doctors usually recommend regular prenatal monitoring, including monitoring of the fetal heart rate. This can be achieved using a fetal heart monitor belt, which is typically an elastic band equipped with sensors placed on the pregnant woman's abdomen to detect and record the fetal heart rate. This helps assess whether the fetus is experiencing oxygen deprivation or fetal distress in utero. The use of the fetal heart monitor belt usually begins around week 36 of pregnancy, as this is when fetal cardiac monitoring becomes necessary. The belt is an adjustable strap used during fetal electrocardiographic monitoring to secure electrode patches. However, for high-risk pregnancies—such as those complicated by diabetes, hypertension, or thyroid disorders—the fetal heart monitor belt may be used earlier.

In summary, the specific timing for using a fetal heart monitor belt should be determined based on individual circumstances. Therefore, it is recommended to consult a reputable hospital and follow medical advice before use.
