Fhr variability is represented by the variation in the fhr and it is a marker of fetal well being. The issue is of course what if the baby s heart rate varies between 120 160 bpm.

This is after all where the normal fetal heart rate commonly lies.

Fetal heart rate. From this point it will increase its rate of about three beats per minute per day during that first month. If the heart rate is below 140 bpm then the chances are that the baby will be a boy. Current international guidelines recommend for the normal fetal heart rate fhr baseline different ranges of 110 to 150 beats per minute bpm or 110 to 160 bpm.

Baseline fetal heart rate definition average fhr rounded to 5 bpm during a 10 minute period but excludes periods of marked increased fhr variability segments of baseline that differs by more than 25 bpm must compromise at least 2 minutes out of 10 minute segment normal range is 110 160 bpm nichd always documented as. Fhr variability is represented by the variation in the fhr and it is a marker of fetal well being. 80 85 beats per minute bpm.

At this point a normal fetal heart rate is about the same as the mother s. The fetal heart rate is between 90 and 110bpm in early pregnancy 7. If the baby s heartbeat is not audible for a week or more miscarriage is likely to happen.

We started with a precise definition of normality and performed a retrospective computerized analysis of electronically recorded fhr tracings. Following this the heartbeat becomes normal and stabilizes between 120 and 160bpm during the second and third trimesters. A fetal doppler is a test that uses sound waves to check your baby s heartbeat.

The normal fetal heart rate fhr pattern has a baseline rate of 120 to 160 beats per minute. A normal fetal heart rate fhr usually ranges from 120 to 160 beats per minute bpm in the in utero period. This theory states that if the fetal heart rate is above 140 beats per minute bpm then the baby is more likely to be a girl.

A fetal heart rate range of 100 160 is considered as normal. At about five weeks gestation your baby s heart begins to beat. 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.

If the baby s heartbeat is not audible for a week or more miscarriage is likely to happen. It will then rise and peak around the 9th and 10th week to 170 bpm. It s a type of ultrasound that uses a handheld device to detect changes in movement that are translated as sound.
