What is the normal range for fetal heart sounds?
Fetal heart rate refers to the heart rate of the fetus, and its normal range should be 110-160 beats per minute. Some pregnant women may find that the fetal heart rate is too fast when measuring it. In this case, continuous monitoring is required, which may be due to exercise or other reasons, and the second monitoring will return to normal. If the fetal heart rate remains excessively fast, it indicates intrauterine hypoxia, which can be improved by oxygen inhalation for pregnant women.
1. Normal Range of Fetal Heart Rate
The normal fetal heart rate is 110 to 160 beats per minute, with regular rhythm and moderate strength, resembling the ticking sound of a clock.
2. Excessively Fast Fetal Heart Rate
If the fetal heart rate occasionally exhibits tachycardia or bradycardia, it is generally normal, possibly caused by the fetus being in a state of movement or sleep. However, if such conditions persist for a long time, a medical examination should be performed. If intrauterine hypoxia is the cause, timely oxygen inhalation is necessary.
3. Excessively Slow Fetal Heart Rate
A fetal heart rate below 120 beats per minute is more dangerous because when a fetus is hypoxic, its heartbeat first accelerates and then gradually slows down.
4. Time for Monitoring Fetal Heart Rate
It is recommended that pregnant women start checking the fetal heart rate from the 34th week of pregnancy, with a general recommendation of once a week. During pregnancy, it is essential to avoid overexertion, emotional excitement, ensure adequate sleep, and regularly attend prenatal checkups at the hospital.
