fetal heart rate

fe·tal heart rate (FHR),

in the fetus, the number of heartbeats per minute, normally 120-160.

fetal heart rate (FHR)

the number of heartbeats in the fetus that occur in a given unit of time. The FHR varies in cycles of fetal rest and activity and is affected by many factors, including maternal fever, uterine contractions, maternal-fetal hypotension, and many drugs. The normal FHR is between 110 beats/min and 160 beats/min. In labor the FHR is monitored with a fetoscope, an electronic fetal monitor for detecting abnormal alterations in the heart rate, especially recurrent decelerations that continue past the end of uterine contractions.

fetal heart rate

Obstetrics A rate which, in the non-stressed fetus, reflects cardioaccelerator and cardiodecelerator reflexes; analysis of the FHR requires evaluation of a baseline FHR between uterine contractions or periodic changes in the FHR and non-periodic, short-term fluctuations in the FHR. See Deceleration.
