What is fetal heart rate monitoring?

Hello, fetal heart rate monitoring (also known as cardiotocography or CTG) allows observation of the fetal heart rate and its changes in response to fetal movement or uterine contractions. At six months’ gestation, routine fetal heart rate monitoring is generally not required; it is typically initiated no earlier than eight months into pregnancy. At your current stage, a 4D ultrasound examination is recommended to screen for fetal structural abnormalities—including congenital cardiac defects. We advise you to attend regular prenatal check-ups at the hospital. I hope this information is helpful. Wishing you good health!
