Is weak fetal heart dangerous?

Fetal heart is one of the important signs to know the health status of the fetus. So if the fetal heart is weak, is it dangerous? Weak fetal heart what to do?

Normal fetal heart rate will be about 120-160 beats/minute. At the 5th - 6th week of pregnancy, the average heart rate can be 110 beats/min and gradually increases at 9-10 weeks, about 170 beats/min. By the 14th week of pregnancy, the fetal heart rate tends to decrease gradually, to about 150 beats / min and when it comes to the last months of pregnancy, the fetal heart rate is 130 beats / min

Fetal heart failure is usually defined as the fetal heart rate below 110 beats/min. Cardiac arrhythmias can range from mild to severe, depending on gestational age, the underlying cause, and the condition of the individual fetus, including any associated complications.

But if unfortunately your case falls into a small percentage, the fetal heart rate is severe, the fetal heart rate is prolonged and can be life-threatening, putting the fetus at risk of NIHF (external fluid retention). vessels or body cavities) and heart failure, stillbirth. The slower the fetal heart rate and the earlier it occurs in pregnancy, the higher the chance of miscarriage. During the first trimester, fetal heart failure increases the risk of miscarriage. Below 70 beats/min, the rate is almost 100%, at 90 beats/min, the miscarriage rate is 86%, below 120 beats/min, this rate only drops to 50%.

In many cases, fetal heart failure is associated with other pathologies, including congenital heart defects (neurological defects, fetal heart defects), obstruction of the umbilical cord feeding, early pregnancy fetal compression in the pelvis, maternal connective tissue disease (systemic lupus erythematosus) and chromosomal abnormalities, uterine rupture, placental anomaly, maternal heart failure, kidney failure, diabetes, etc. ..
