Poor fetal heartbeat may result in fetal growth retardation, fetal hypoplasia, and fetal arrest.
Normal fetal heart rate is 110~160 beats per minute, bad fetal heart may be the fetal heart rate persistently lower than 110 beats or the fetal heart rate persistently higher than 160 beats per minute, in the bradycardia or tachycardia persisting for more than 10 minutes are not normal phenomenon.
A poor fetal heartbeat may lead to intrauterine hypoxia, which may result in intrauterine growth retardation if left uncorrected for a long time.
Poor fetal heartbeat may also be caused by poor fetal development, such as congenital heart disease, which should be determined by 4D ultrasound or cardiac ultrasound.
In serious cases, a poor fetal heartbeat that lasts too long may cause the fetus to stop developing in the uterus, and the pregnant woman will not be able to continue the pregnancy.
It is important to have a good pregnancy checkup to know if the fetus is developing normally in the womb.
