Abstract

We describe the case of an asymptomatic young pregnant woman with a diagnosis of congenital long QT syndrome type II in the context of in utero fetal 2:1 heart block and ventricular tachycardia. The presentation, clinical considerations, and management of the mother and baby in the antepartum and postpartum periods are discussed.

Keywords: congenital long QT syndrome; fetal ventricular tachycardia.
