Few people know when the fetus has a palpitation. Since the fifth week of pregnancy, the heart only slightly pulsates, and by the end of the eighth week it becomes four-chambered and works full-fledged.
Typically, the first ultrasound is done at 12 weeks, but at a period of 5 to 6 weeks, you can make a transvaginal ultrasound that gives you the opportunity to hear the first heartbeat of the fetus. Further, this process is followed by a doctor who leads a woman's pregnancy. And to listen to the heartbeat of the fetus, he uses a special device, which is made of wood, so it passes the sounds quite well.
But the baby's heart does not always work normally. Delayed or too quick his work testifies to certain violations in the development of the child.
Muted fetal heart beat
The normal rhythm of the work of the future baby's heart is 170-190 beats per minute for a period of 9 weeks, and after the eleventh week the number of strokes decreases to 140-160 strokes. But if the fetus has a weak palpitation, that is, less than a hundred beats per minute, then it is necessary to carry out treatment aimed at eliminating the problem that caused the slowing of the heart rate.
There are cases when the fetus does not listen to the heartbeat. This can be caused by the following factors:
- many or little water;
- excess thickness of the anterior abdominal wall for obesity of the mother;
- multiple pregnancy;
- increased fetal activity.
