Heartbeat of the fetus
The heartbeat of the fetus is one of the most important signs in which the fetus is healthy and stable. At the beginning of the third week of pregnancy, the heart is initially formed from two blood vessels. However, the heart does not start functioning. Of pregnancy, and at the beginning of the sixth week begins the first heartbeat of the fetus, and starts blood circulation, then parents can hear the sound of the heartbeat of their child by ultrasound, and by the end of the twentieth week can be heard heartbeat of the fetus by the earpiece of the doctor.
At first the heartbeat of the fetus is light, it does not exceed 100 beats per minute, and every week passes the fetus, the fetal heartbeat increases continuously, to 195 beats per minute in the ninth week of pregnancy, to settle in the twelfth week and be Between 120-160 beats per minute.
Factors affecting pulse hearing
Some women complain of not hearing the heartbeat of their fetus in the sixth week of pregnancy, and consider it a sign of danger, but in fact, the heartbeat of the fetus varies from one woman to another, and factors that affect not hearing the pulse of the fetus:
- Severe noise at the examination site.
- Thickening of the woman’s uterine wall that would affect the hearing of the fetal pulse.
- Amniotic fluid surrounding the fetus.
- The accuracy of the devices used, and the correct calculation of the date of pregnancy.
Signs of fetal heart failure
In many cases, doctors are unable to determine the causes of the fetal heart failure before birth. However, some doctors refer the cause to several factors, such as: wrapping the umbilical cord around the fetus’s neck, fetal malformations, maternal health problems, and other factors.
Although there are no signs that warn the mother of the possibility of the death of her fetus in her womb, there are some signs that may indicate the existence of a problem, including:
- Stop fetal movement.
- Drops of blood in the first stage of pregnancy, or vaginal bleeding in the second half of pregnancy.
- Mother’s sense of danger to her fetus.
- The disappearance of symptoms of pregnancy, especially the flesh, if it eased or disappeared completely before the end of the first stage of pregnancy means that there is a problem.
What should be taken into account is that these previous symptoms are not considered to be a diagnosis of fetal death, and the best way to diagnose this is television imaging.
