title: Spontaneous ventricular tachycardia and fibrillation in a patient with a positive microvolt T wave alternans test and negative electrophysiological study.
abstract: This report describes a patient with a previous myocardial infarction who presented with syncope. The patient had a positive microvolt T wave alternans test, a negative electrophysiological study, and a normal heart rate variability. In hospital, the patient had episodes of ventricular tachycardia and fibrillation. An implantable cardioverter defibrillator was implanted and during the following week it discharged appropriately.
