The quantification of intrapartum fetal heart rate (FHR) patterns in normal healthy neonates yielded 17 FHR variables: seven of these measures have not been reported previously. A factor analysis was performed on the 17 FHR variables in order to identify the pattern of interrelationships among them. This analysis resulted in a 6‐factor Varimax solution. The factors, in order of variance accounted for, were descriptively labeled deceleration, complexity, frequency, baserate, acceleration, and variability. The results support the hypothesis that the FHR response to labor is a multi dimensional phenomenon. Specifically, different parameters, i.e., amplitude, frequencies, etc., tended to be uncorrelated across subjects.
