A normal nonstress test will show a baseline fetal heart rate between 110 and 160 beats per minute with moderate variability (5- to 25-interbeat variability) and 2 qualifying accelerations in 20 minutes with no decelerations. "Reactive" is defined as the presence of two or more fetal heart rate accelerations within a 20-minute period. Each ...
NST is typically monitored for at least 20 minutes. Signs of a reactive (normal) NST include a baseline fetal heart rate (FHR) between 110 and 160 beats per minute (bpm) and 2 accelerations of FHR of at least 15 bpm above baseline for over 15 seconds. Vibroacoustic stimulation and longer monitoring may be needed if NST is non-reactive. [28]

These periods are divided into three stages. The first stage occurs in the first 30 minutes of life; during this stage the infant is alert and responsive with heart rate peaking at 160-180 beats per minute and then stabilizes to a baseline rate of 100-120 beats per minute. Crackles upon auscultation and irregular respirations are a normal finding.
The normal heart rate of the fetus is between 110 and 160 beats per minute. Any rhythm beyond these limits is abnormal and classed as a fetal arrhythmia. These are mainly the result of premature atrial contractions, usually give no symptoms, and have little consequence.
What’s a normal heart rate? A “normal heart rate” for adults ranges from 60-100 beats per minute (bpm), says Brett Victor, M.D., F.A.C.C., cardiologist at Cardiology Consultants of ...
A Zigzag pattern of fetal heart rate (FHR) is defined as FHR baseline amplitude changes of more than 25 beats per minute (bpm) with a minimum duration of 2 minutes and maximum of 30 minutes. [19] However, according to another study, even a >1 min duration of the zigzag pattern is associated with an increased risk of adverse neonatal outcomes. [21]
Those are times to seek out help because it may not be a reflection of your resting heart rate, but an abnormal heart rhythm that should get evaluated.” Having a pulse over 100 bpm is called ...
