A normal heart rate for a fetus can range from 110 to 160 beats per minute (BPM). Very early in pregnancy, it is typically around 110 BPM. Fetal heart rate may speed up to 140 to 170 BPM around the ninth week and slow to around 110 to 160 BPM thereafter.
A normal fetal heart rate (FHR) usually ranges from 120 to 160 beats per minute (bpm) in the in utero period. It is measurable sonographically from around 6 weeks and the normal range varies during gestation, increasing to around 170 bpm at 10 weeks and decreasing from then to around 130 bpm at term.

What's a normal fetal heart rate? Most experts consider between 110 and 160 bpm (beats per minute) to be a normal fetal heart rate through most of pregnancy. (Some use 110 to 150 bpm or 120 to 160 bpm.) Very early on – between 8 weeks and 10 weeks pregnant – the range is higher, between 150 and 170 bpm. But the rate doesn't stay the same.
By the beginning of the ninth week of pregnancy, the normal fetal heart rate is an average of 170 bpm, up from about 110 at 5 weeks gestation. After 13 weeks gestation, it begins a rapid...
What's the normal fetal heart rate? Learn the ideal heart rate ranges by week in utero, plus whether it can predict baby's sex.
The average fetal heart rate is between 110 and 160 beats per minute. It can vary by 5 to 25 beats per minute. The fetal heart rate may change as your baby responds to conditions in your uterus. An abnormal fetal heart rate may mean that your baby is not getting enough oxygen or that there are other problems.
By the beginning of the 9th week of pregnancy, the normal fetal heart rate is an average of 175 bpm (beats per minute). At this point, a rapid deceleration of the fetal heart rate begins, reaching around 110-160 beats per minute in mid-gestation.
