Does fetal heart rate change when fetus grows up?

Fetal heart rate in 120 ~ 160 times / min, sometimes faster, also not very regular, to the end of pregnancy more regular. Sometimes there will be a short pause, or the speed reaches 180 times / min, which is a normal phenomenon.

The normal fetal heart rate is between 120-160 beats per minute, occasionally slightly faster or slower. If the fetal heart rate is maintained for more than 10 minutes, less than 120 beats per minute or more than 160 beats per minute, it indicates that the fetal heart rate is abnormal.

Most cases of abnormal fetal heart rate is on behalf of fetal hypoxia in the uterus. The more serious the abnormal fetal heart rate is, the more severe the fetal hypoxia is. But not all abnormal fetal heart rate is caused by hypoxia. In addition to fetal hypoxia, the disease, mood and exercise of pregnant women also affect the change of fetal heart rate. For example, pregnant women with fever or hyperthyroidism, fetal heart rate often appear more than 160 times per minute.
