Fatal heart monitoring and ultrasound in the management of placental abruption

Abstract Three cases of placental abruption with the “pseudosinusoidal” fetal heart rate (FHR) pattern, a periodic late deceleration related to frequent uterine contractions are reported. This ‘pseudosinusoidal’ pattern is clearly not a true sinusoidal pattern. The fetal monitoring patterns of these patients are presented and discussed along with the use of ultrasound in the management of this condition. All infants were delivered by cesarean section with low Apgar scores at birth, but they soon recovered completely.
