In a healthy labor and delivery, the baby’s heart rate will drop slightly during a contraction, and then quickly return to normal once the contraction is over (2). Therefore, some variability in heart rate is to be expected: this shows as a jagged line on the monitor.
What causes fetal heart rate drop?
A slow fetal heart rate is typically caused by problems with the heart’s electrical system, which sends out electrical impulses that signal the heart muscles to contract or beat. The problem can occur in the sinus node, the heart’s natural pacemaker, where these electrical impulses are generated.
What do you do when your baby’s heart rate drops?
If your baby’s heart rate is very rapid or dips down, there are some simple changes your doctor may suggest:
- Changing your position.
- Giving you more fluids through an IV.
- Giving you supplemental oxygen.
When does a baby’s heart rate slow down?
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 does low fetal heart rate indicate?
A slower than expected fetal heartbeat referred to as fetal bradycardia can mean higher odds of miscarriage, but it also may be due to the pregnancy not being as far along as estimated.

How can I check my baby’s heart rate at home?
Turn the doppler on and slowly — really slowly — move it around until you can hear the heartbeat. The earlier it is in your pregnancy, the lower you’ll likely have to go. Try below your belly button. Be aware that you’ll also hear your own heartbeat and the pulse of an artery.
