Abstract:
The sinusoidal fetal heart rate pattern is a phenomenon of elusive pathophysiologic features and uncertain clinical significance. We present a case of sinusoidal fetal heart rate that occurred in association with fetal breathing. The degree and type of synchrony between the sinusoidal fetal heart rate and breathing movements suggest that the sinusoidal fetal heart rate and the respiratory sinus arrhythmia are related phenomena.
