title: Coexistence of kent accessory pathway, enhanced AV node conduction, and various conduction disturbances in a young athlete with tricuspid valve dysplasia.
abstract: An asymptomatic 19-year-old top-level athlete had electrocardiographic evidence of intermittent cardiac preexcitation and intermittent left bundle branch block. The electrophysiologic study demonstrated the presence of a direct accessory pathway and enhanced atrioventricular node conduction that resulted in infrahisian and intraventricular conduction disturbances. The echocardiogram disclosed tricuspid valve dysplasia.
