When the B -ultrasound is checked, the fetal heart beating can be displayed from the B -ultrasound’s fluorescent screen.

After 8 weeks of pregnancy, fetal heartbeat can reach about 180 times per minute.After 14 weeks of pregnancy, the fetal heartbeat speed drops by about 140 times per minute, and it will remain at 120 to 160 times per minute.

At about four months of pregnancy, fetal heart sounds can be heard near the middle of the umbilicus. In the future, with the growth of the fetus and the different fetal position, the position of the fetal heart will change.Because the heart sound of the fetal heart is more out of the fetus, it can be heard most clearly at the back of the fetus.Can be listened to the middle line of the umbilical or under the abdomen of the umbilical.

The fetal heart sound should be different from the uterine arteries and placenta noise.The uterine arterial noise is a blow -like bass produced by the blood flow through the expansion of the uterine arteries. The placenta noise is produced by the blood flow when the placenta passs through the placenta.The scope of the placental noise is larger than the range of the arterial murmur.
