Fetal heart rate of 176 beats/minute at 13 weeks of pregnancy is not normal and belongs to the condition of excessive fetal heart rate. Thirteen weeks of pregnancy belongs to the early stage of pregnancy, the normal fetal heart rate is 110~160 beats/min, the fetal heart rate of 176 beats/min suggests that the fetal heart rate is accelerated, which may be due to the localization of the fetal trunk or the umbilical vein is temporarily compressed. Stimulated by fetal movement, contractions, etc., the fetal heart rate may briefly accelerate or slow down, and if it then quickly returns to normal, no special treatment is needed. However, if the umbilical vein continues to be compressed, it develops into a deceleration of the fetal heart rate, which may indicate that the fetus is suffering from hypoxia. A fetal heart rate of 176 beats per week at 13 weeks’ gestation is considered to be an accelerated fetal heart rate, and should be closely monitored at the hospital.
