Fetal heart rate of 170 beats per minute during fetal movement may be normal, or it may be a sign of fetal hypoxia. Fetal movement is generally between 110-160 beats per minute. The increased activity of the fetus during fetal movement may stimulate the nerves and cause a transient increase in the fetal heart rate, and the heart rate will return to the normal range after a period of time. If the fetal heart rate remains at 170 beats per minute for a long time after fetal movement, then we need to be vigilant to rule out the possibility of fetal hypoxia that excites the sympathetic nerves, which may lead to fetal distress and fetal tachycardia. This is not normal and the cause needs to be identified as soon as possible. Every pregnant woman should pay attention to do a good job of prenatal checkups during pregnancy, and actively listen to the advice of professional doctors to do a good job of comprehensive care and health care, which can effectively ensure the safety of the birth.
