Sporadic fetal heart rate decelerations in preterm pregnancies and adverse obstetrical outcomes

Abstract

Sporadic fetal heart rate decelerations (SFHRD), observed in a Non-Stress Test (NST), in low-risk pregnancies at term, is associated with an increased risk of adverse pregnancy outcomes. However, the significance of SFHRD, observed in preterm pregnancies, is still unknown. Our objective was to evaluate whether SFHRD observed in a NST performed at 28-37 weeks of gestation is associated with adverse obstetrical outcomes.
