note = "The purpose of this study was to assess placental vascular resistance as measured by peak systolic to end-diastolic ratios (S/D) of the umbilical artery waveforms in patients with late decelerations. Fifty patients with persistent late decelerations and 50 gestational age-matched controls with reactive tracings underwent umbilical velocimetry with measurement of S/D ratios.",
