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. Evolution through gestation
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.
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 ...
Your healthcare provider may do fetal heart monitoring during late pregnancy and labor. 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.
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.
Continuous feedback-based training of healthcare professionals, a low threshold for echocardiography referrals, use of standardized ultrasound protocols and easy access to fetal-heart specialists can improve the performance of a screening program 14, 24 - 26.
Continuous fetal monitoring, or cardiotocography, is a method of tracking the fetal heart rate (FHR) along with the occurrence of uterine contractions. The relationship between these two variables is widely accepted to correlate with the oxygenation status of the fetus.
The normal rate is generally considered to be between 120 and 160 beats per minute. The rates are typically higher (140-160) in early pregnancy, and lower (120-140) toward the end of pregnancy. Past term, some normal fetal heart rates fall to 110 BPM.
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. There is also a slow deceleration in fetal heart rate in the last ten weeks of pregnancy.
A normal fetal heart is between 120 and 160 beats per minute. (source) This is a lot faster than most parents expect to hear. In fact, it’s almost twice that of an adult heartbeat. But it’s important to note that the heart rate can, and does, change depending on the gestational age of the baby.
