Fetal/neonatal supraventricular tachycardia.
At 38 weeks of gestation, a woman with a previously unremarkable pregnancy was noted to have fetal tachycardia without obvious cause. Fetal echocardiography resulted in a presumptive diagnosis of fetal atrial flutter with a 2:1 block. The newborn resumed the same rhythm. The neonate underwent transesophageal incremental overdrive pacing. A normal sinus rhythm was restored. The infant had no recurrence to age 6 months.
