Normal Fetal Heartbeat. By 6 weeks your baby s heart now beating 110 times a minute has four hollow chambers each with an entrance and an exit to allow blood to flow in and out of each chamber. At this point a normal fetal heart rate is about the same as the mother s. It will then rise and peak around the 9th and 10th week to 170 bpm. 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. A normal fetal heart is between 120 and 160 beats per minute. By 6 weeks your baby s heart now beating 110 times a minute has four hollow chambers each with an entrance and an exit to allow blood to flow in and out of each chamber. Following this the heartbeat becomes normal and stabilizes between 120 and 160bpm during the second and third trimesters. The fetal heart rate is between 90 and 110bpm in early pregnancy 7. That s about twice as fast as yours.
It will then rise and peak around the 9th and 10th week to 170 bpm.
We started with a precise definition of normality and performed a retrospective computerized analysis of electronically recorded fhr tracings. 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. A fetal heart rate range of 100 160 is considered as normal. By 6 weeks your baby s heart now beating 110 times a minute has four hollow chambers each with an entrance and an exit to allow blood to flow in and out of each chamber. It will then rise and peak around the 9th and 10th week to 170 bpm. 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.
