title: [Incessant ventricular tachycardia as a manifestation of myocardial ischemia].
abstract: We describe four patients with incessant ventricular tachycardia after the acute phase of a myocardial infarction. Two of them had a slow heart rate, and myocardial revascularization resolved the arrhythmia after ischemia was demonstrated. In the other two cases, very fast tachycardias were interrupted by means of intravenous verapamil and clinical stabilization was achieved after failure of amiodarone and lidocaine. In one of them, revascularization prevented new recurrences, but it was not feasible in the second patient, who developed new arrhythmias. The possible mechanisms of these tachycardias and their clinical and therapeutic implications are discussed.
