summary

I have been pregnant for six months now. Before, maybe the baby in my stomach was still small, so I didn't feel much. Recently, I just learned to measure the baby's fetal heart rate. The result shows that the baby's fetal heart rate is different from the normal value, which is really worrying. Now let's talk about whether the irregular fetal heart rate in the second trimester is normal.

Is the second trimester fetal heart rate abnormal

First: fetal heart rate: fetal heart rate is the frequency of fetal heart beat. The normal fetal heart rate is 120-160 beats / min, sometimes faster and irregular, and it will be more regular at the end of pregnancy. Sometimes there will be a short pause, or the speed reaches 180 times / min, which is a normal phenomenon. However, if this phenomenon occurs frequently and for a long time, timely medical consultation is needed.

Second: the fetal heart sound is usually heard in the abdominal wall of pregnant women above the back of the fetus. Due to the different position of the fetal head, the location of the loudest heart sound is also different. Expectant mothers need to learn to count the fetal heart rate per minute. If the fetal heart rate is less than 120 beats / minute or more than 160 beats / minute, it means that the fetal heart rate is abnormal, and further review and monitoring are needed.

Third: the situation of the mother to be also affects the change of fetal heart rate, such as fever, fetal heart rate will often exceed 160 times / min; hyperthyroidism, pregnant women's heart rate is very fast, fetal heart rate is often more than 160 times / min; if you take some drugs, such as shuchuanning taken during preterm birth, or atropine, can cause maternal and fetal heart rate to accelerate.
