Abstract

Fetal tachyarrhythmia may occur in 0.4-0.6% of pregnancies. Supraventricular tachycardia (SVT) is the most frequently reported fetal tachyarrhythmia. Fetal SVT is rhythm disturbance characterized by 1: 1 atrioventricular conduction at a rate between 220 and 300 beats per minute. Digoxin is most common first –line antiarrhythmic agent for fetal SVT, but there is no consensus on the most effective secondary agent. We report here a case of SVT at 23 weeks of gestation failed treatment of maternal digoxin and sotalol combination and review management guidelines in the literature.
