In pregnancy, the fetal heart rate fluctuates. After the 13th week of pregnancy, it gradually slows down. It is fastest at roughly 9 weeks gestation. The fetal heart rate, however, continues to beat more quickly than the adult heart rate. 1 Many pregnant women may worry what fetal heart rate is normal—and what is not—especially after hearing their baby's heartbeat at a prenatal appointment. You might be really surprised by what you hear. The majority of individuals are unprepared for how swiftly a baby's heart beats throughout pregnancy. Most scientists and medical professionals define a normal fetal heart rate as being between 110 and 160 beats per minute (bpm), however some experts use more specific ranges, such as 110 to 150 bpm or 120 to 160 bpm [1].

Although there are various ways to describe the first time you hear your baby's heartbeat, the majority of people refer to it as "galloping" when they describe the sound it makes. Although a pregnant woman's heart rate is higher than that of an adult, a normal fetal heart rate fluctuates throughout the day and throughout the stages of pregnancy. The average foetal heart rate at the beginning of the ninth week of pregnancy is 170 bpm, up from roughly 110 at five weeks gestation. It rapidly slows down to the typical fetal heart rate for mid-pregnancy, which ranges from 110 to 160 bpm, about 13 weeks of gestation. The normal fetal heart rate likewise slows down in the final 10 weeks of pregnancy, albeit it is still almost twice as high as the average adult's resting heart rate. A fascinating finding from studies is that male and female fetuses have different fetal heart rates as pregnancy progresses, with female fetuses having considerably greater heart rates. You can hear the swings if you are having a non-stress test toward the end of your pregnancy. Within a particular range of normal, the heart rate fluctuates. Imagine what it would sound like to continuously hear your heart rate as you began your workout and finished it. Your heart rate would also fluctuate. Your infant responds in the same way [2].

Fetal heart rate monitoring is generally secure. However, the majority of medical professionals agree that ongoing monitoring is not required for pregnancies with little risk of problems. Your movement may be limited by continuous electronic fetal monitoring, which is advantageous during labor. Additionally, it raises the possibility of an unneeded caesarean delivery or a delivery requiring forceps or a vacuum equipment[3].

We found that "normal" ranges normalcy in a statistical sense are 120 to 160 bpm after analyzing about 1.5 billion individual single baseline fetal heart rate readings from 78,852 CTG tracings in three German medical facilities. By providing a data-driven definition of the normal FHR, we hoped to lay the groundwork for a clinically significant endeavor to eventually lower the rate of false alarms in CTG monitoring in general and electronic decision support systems in particular. Ineffective interventions like caesarean sections might be avoided as a result. In keeping with the findings of other studies, our analysis's FHR baseline shows a modest decline during gestation. This empirical observation is compatible with well-documented physiological alterations in fetal development, mostly as a result of the growing opposite effect [4].
