Normal fetal heartbeat is 110-160 beats per minute. If the fetal heartbeat is 130, it means the baby’s fetal heartbeat is normal. Usually after the baby moves, the fetal heart increases, about 15 times. At 36 weeks of pregnancy, we can do fetal heart monitoring to monitor the baby in the womb and see if the baby is hypoxic. The fetal heart monitoring should be done for at least 20 minutes, and there should be at least 3 fetal movements within 20 minutes, and the fetal heart also has to accelerate 15 times during the fetal movement, and the acceleration should last for 15 seconds, so that the baby’s reserve capacity is considered good. The baseline fetal heart rate should also be 110-160 beats per minute. The fetal heart monitoring should also be done to see if there are contractions, if there are contractions also to see the baby’s fetal heart condition during the contractions, if the fetal heart decreases during the contractions, it is early deceleration. If the baby’s heart rate drops after a contraction, it is a late deceleration. The late deceleration may indicate that the baby is suffering from oxygen deficiency in the womb.
