Fetal heart rate changes throughout pregnancy. Its fastest at around 9 weeks gestation then gradually slows after the 13th week of pregnancy. But fetal heart rate by week remains faster than an adult heart rate. Many pregnant people, particularly after hearing their babys heartbeat[1] at a prenatal visit, may wonder what fetal heart rate is normal—and whats not. What you hear might really surprise you. Most people are not prepared for how quickly a babys heart beats in pregnancy.

Most researchers and doctors define normal fetal heart rate as between 110 to 160 beats per minute (bpm), with some experts using narrower parameters, such as 110 to 150 bpm or 120 to 160 bpm.
