High fetal heart rate may have a heart disease, but it may also be caused by fetal movement, fever, intrauterine hypoxia and other reasons.
Fetus has heart disease, there may be increased fetal heart rate in pregnancy, but not absolute, this situation is not specific, many abnormal heart development of the fetus in pregnancy does not have obvious abnormal reaction, fetal heart rate is not necessarily high.
Fetal heart rate is not a direct diagnosis of heart disease, only through the fetal ultrasound examination can determine whether there are defects in the development of the fetal heart.
Normal fetal heart rate is 110-160 beats per minute. Fetal heart rate of more than 160 beats per minute is considered to be high, and there are many reasons for high fetal heart rate. Fetal heart rate will be high after the fetus is active in the uterus, and high fetal heart rate will also be caused by increased body temperature after the pregnant woman has a fever, and fetal hypoxia due to the umbilical cord wrapping around the neck or the umbilical cord tying up, etc. Fetal heart rate will also have a high manifestation.
Fetal heart rate is high, but the duration is short, soon return to normal can not indicate fetal abnormality, high fetal heart rate lasts for more than 10 minutes to guard against fetal abnormality, we should consult a doctor for further examination.
