After a woman is pregnant, the fetus in her belly will grow up day by day, and the body organs of the fetus will gradually develop, and the signs of life will become more and more obvious. Among them, the heart develops earliest, and pregnant women first perceive fetal heart sounds through examination. We can learn about the growth of the fetus through the fetal heart sound. If the fetal heart sound is abnormal, it needs to be treated in time to make the fetus grow safely. What is the normal range of fetal heart?
Generally speaking, if the menstrual period before pregnancy is normal, the fetal heart rate and embryo bud can be seen by ultrasound about 50 days after pregnancy, but if you want to hear the fetal heart rate with a stethoscope, it will take about two or three months, that is, from the eighth week to the twelfth week after pregnancy. If the pregnant woman is pregnant 1 1 week, you can hear the fetal heart rate with a stethoscope.
However, the fetal heart rate will have a certain frequency. The normal heart rate of the fetus is 120~ 160 beats per minute. When the fetus is less than 20 weeks old, the fetal heart rate will be faster. When the fetus is older, the fetal heart rate will be relatively slow. Moreover, after fetal movement, the fetal heart will accelerate temporarily, which may reach more than 160 times per minute, but it is very high. However, if the fetal heart beats more than 160 times per minute, or less than 120 times, we need to pay attention to it, because this is an abnormal situation and we should go to the hospital for treatment in time.
When the fetal heart rate is abnormal, pregnant women should go to regular hospitals for physical examination in time to find out the causes of abnormal fetal heart rate. Only by clarifying the reasons can we prescribe the right medicine and let the fetal heart rate return to normal as soon as possible. At the same time, in daily life, we should pay more attention to the health of pregnant women, let pregnant women have regular checkups, let pregnant women get timely treatment when abnormal conditions occur, and let the fetus grow up healthily.
