Sinusoidal Heart Rate Pattern And An Normal Biophysical Profile In A Severely Compromised Fetus

Abstract

A case is described in which a woman complained of weakened fetal movements, and a persistent sinusoidal heart rate pattern was demonstrated in the presence of normal fetal breathing movements, normal fetal tone, and normal amount of amniotic fluid. In view of the subjective complaints and disregarding the normal biophysical profile, termination of pregnancy was performed. A compromised, severely anemic fetus was delivered by cesarean section. The role of sinusoidal heart rate pattern and the limitations of biophysical scores as a single determinant of fetal well being are discussed.
