The authors report the case of a young man with idiopathic ventricular tachycardia occurring in bursts and arising from the pulmonary infundibulum. During follow-up, progressive, severe, dilated cardiomyopathy was observed. Radiofrequency ablation of the site of origin of this very active arrhythmia resulted in total regression of the cardiomyopathy. Contrary to generally accepted concepts, paroxystic ventricular tachycardia, usually qualified as benign, may be complicated by cardiomyopathy when the ventricular extrasystole is incessant and repetitive.
