title: Sinusoidal fetal heart rate.
abstract: Two cases with sinusoidal fetal heart rates (SHR) with good perinatal outcome are reported. Since nonstress tests, oxytocin challenge tests and serum free estriols were normal, SHR was considered not indicative of fetal compromise. A SHR can occasionally be found in connection with reactive nonstress test. In those cases it may be of minor importance when compared to the situations when the tracing also shows a nonreactive nonstress test and the perinatal outcome is often poor.
