A forty-year-old man was admitted to our hospital because of dizziness, palpitations and an oppressive feeling in the precordium. Physical examination was normal. A chest roentgenogram revealed mild cardiomegaly and the electrocardiogram showed ventricular tachycardia of a left bundle branch block configuration which was terminated by the intravenous injection of procainamide. During sinus rhythm the electrocardiogram showed incomplete right bundle branch block, PQ prolongation and inverted T waves in leads V1 through V3. Two-dimensional echocardiography revealed only moderate right ventricular dilatation. Right ventricular angio-graphy showed severe right ventricular dilatation and hypokinesis of the right ventricular apex and pulmonary artery infundibulum. From these characteristic signs we concluded that this adult patient had arrhythmogenic right ventricular dysplasia (ARVD), suggesting that this condition is not confined to children but may occur in adults as well.
