A fetal heart rate of 120 beats/minute is generally normal. The normal value of fetal heart rate is usually 110 to 160 beats/minute, so 120 beats/minute is a normal fetal heart rate. Fetal heart generally refers to the heartbeat of the fetus, which can reflect the state of the fetus in the uterus. When the fetus is deprived of oxygen, the fetal heart rate may be too fast or too slow. Doctors can determine the health of the fetus by the fetal heart rate. If it is below 110 beats per minute or above 160 beats per minute, it means that the fetus may be showing signs of oxygen deprivation. The fetal heart rate can usually be heard by a Doppler fetal heart rate monitor at around 12 weeks of pregnancy. However, in early pregnancy, the fetal heart rate is relatively fast and may reach 170 to 180 beats/minute, which is also normal. Therefore, a fetal heart rate of 120 beats/min is normal. If during pregnancy, the fetal heart rate deviates significantly from the above range, it is recommended to consult a doctor in a timely manner, and under the guidance of the doctor, complete the relevant examinations to clarify the cause of the disease and provide symptomatic treatment.
