title: Sinusoidal versus pseudosinusoidal fetal heart rate patterns.
abstract: Reports on fluctuating fetal heart rate (FHR) patterns, which have been called sinusoidal FHR patterns in the literature, have been critically reviewed. Based on this analysis, stricter criteria are presented whereby the true sinusoidal pattern can be diagnosed and distinguished from the pseudosinusoidal pattern. A practical approach to the interpretation and management of fluctuating FHR patterns is presented.
