Baby’s fetal heart rate of 157bpm is normal. Fetal heart rate between 110-160bpm are normal ranges, while also depending on the week of pregnancy. If the fetal heart rate is too high or too low, it is important to be on the lookout for intrauterine hypoxia. Fetal heart rate monitoring is usually required every week after 36 weeks of pregnancy. General checkups can be done with a fetal heart stethoscope or Doppler fetal heart rate monitor to determine how the fetus is doing in the womb. If abnormalities of the fetal heart are detected, it is necessary to follow the doctor’s instructions for symptomatic treatment, and if necessary, oxygen recheck. After 30 weeks of pregnancy, you can count the fetal movements regularly to detect the development of the fetus in the uterus. If there is any abnormality, you can consult a doctor in time for symptomatic treatment.
