Abstract

We examined 40 patients with ventricular tachycardia (VT) and no evidence of heart disease, and found a 50% prevalence of ventricular late potentials (VLPs) on the signal-averaged electrocardiogram. This finding was associated with a significantly higher content of fibrous tissue on endomyocardial biopsy and a lower right ventricular ejection fraction. Thus, VLPs are frequently found in idiopathic VT, are a marker for subclinical anatomic and functional abnormalities of the right ventricle, and may be associated with a worse outcome.
