Background. With the exception of a few cases such as aborted sudden cardiac death, sustained ventricular tachycardia, and syncope of unexplained origin, there is no consensus on the clinical findings identifying patients with idiopathic dilated cardiomyopathy with an increased risk of sudden cardiac death or malignant ventricular arrhythmias.

To verify whether electrocardiographic and arrhythmologic features could be useful for prognostic stratification, 78 consecutive patients with an invasive diagnosis of idiopathic dilated cardiomyopathy, but without symptomatic ventricular arrhythmias, were enrolled in a prospective study.

Abstract

Background. With the exception of a few cases such as aborted sudden cardiac death, sustained ventricular tachycardia, and syncope of unexplained origin, there is no consensus on the clinical findings identifying patients with idiopathic dilated cardiomyopathy with an increased risk of sudden cardiac death or malignant ventricular arrhythmias. Methods. To verify whether electrocardiographic and arrhythmologic features could be useful for prognostic stratification, 78 consecutive patients with an invasive diagnosis of idiopathic dilated cardiomyopathy, but without symptomatic ventricular arrhythmias, were enrolled in a prospective study. Signal-averaged ECG, 24 to 48 hour ECG monitoring and electrophysiologic study were performed at the time of diagnosis to identify arrhythmogenic predictors of outcome. Transplant-free and arrhythmic event-free survival was evaluated on the basis of initial parameters. Results. During a mean follow-up of 85 months, 9 patients died (6 of sudden cardiac d
