CHRONIC IRREGULAR IDIOPATHIC VENTRICULAR-TACHYCARDIA WITH MYOCARDIAL DYSFUNCTION SUPPRESSED BY VERAPAMIL IN AN ADULT

We report a case of an almost permanent ventricular tachycardia that o ccurred in a 39-year-old man a few weeks before admission to the hospi tal. This arrhythmia was noticeable by its total irregularity and its association with a left ventricular dysfunction. The precise nosologic al frame for the arrhythmia was difficult to define. This case present ed as an idiopathic left ventricular tachycardia, the features of whic h could be consistent with an atypical parasystole. The rapid abolitio n of the rhythm disturbance by oral verapamil without recurrence at 6 months resulted in normalization of the contractile function.
