A 73-year-old man who had a family history of sudden death, experienced syncope. His electrocardiogram (ECG) presented right bundle branch block and right precordial ST segment elevation which are findings identical with those in Brugada syndrome. The cardiac MRI showed right ventricular mild dilatation, and endomyocardial biopsy revealed fatty replacement of myocardial fibers. Though no ventricular tachyarrhythmias were induced during an electrophysiologic test, the effects on ECG of antiarrhythmic agents and autonomic modulations were similar to those in Brugada syndrome. This case may suggest the relationship between Brugada syndrome and right ventricular cardiomyopathy.
