Abstract
Three cases of severely compromised fetuses are reported in which a similar FHR tracing was observed: an undulating pattern describing a “sinusoidal” shape, a frequency of 0.5—1 cpm, amplitude of 10—15 bpm, and flattened baseline varying between 60—120 bpm. This pattern appears to differ significantly from the sinusoidal pattern described previously and appears to identify an agonal or pre-agonal fetus that nonetheless may be salvageable and, therefore, requires maximal obstetric intervention.
