It is not possible to determine whether it is a boy or a girl based on the fetal heart rate, which is 110 to 160 beats. The normal fetal heart rate is 110 to 160 beats. There is no scientific basis for determining a boy or a girl based on the fetal heart rate.
Generally speaking, when the fetus moves more frequently, the fetal heart rate will be faster, while during sleep, the fetal heart rate will be slow, and the fetal heart rate is not fixed.
The normal fetal heart rate is between 110 and 160 beats. If the fetal heart rate exceeds 160 beats, it is called fetal tachycardia. In this case, a test is needed to check for early fetal hypoxia.
If the fetal heart rate falls below 110 beats several times, it is called fetal bradycardia. In this case, fetal heart monitoring is needed to check for fetal hypoxia or cord compression. Fetal heart monitoring is used to determine whether the fetus is in a normal state.
If necessary, ultrasound can be performed under the supervision of a doctor to detect the umbilical cord blood flow rate and the condition of the fetus.
