Abstract
Concern for fetal hypoxia often leads to cesarean delivery when persistent fetal bradycardia is identified. A fetus with premature atrial contractions had a prolonged second-stage heart rate of 80 beats/min. Intrapartum echocardiography and electronic fetal heart rate monitoring distinguished bradycardia caused by blocked atrial bigeminy from hypoxic bradycardia. The fetal scalp stimulation test documented normal acid-base balance and normalized the ventricular rate, avoiding cesarean delivery.
