Paroxysmal ventricular tachycardia appears in a wide spectrum of pathologic situations (1), principally coronary artery disease, but it may occur in the absence of demonstrable heart disease (2). Current studies, based on continuous monitoring, reveal an incidence of 10 to 30% in acute myocardial infarction (3). Paroxysmal ventricular tachycardia has a poorer prognosis when it is associated with digitalis toxicity, acute myocardial infarction, congestive heart failure, shock, or the more severe forms of underlying heart disease (4, 5).
The following case report presents an unusual instance of recurrent paroxysmal ventricular tachycardia, essentially refractory to preventive medical management, and discusses the
