Increased Left Ventricular Dimensions in Patients with Frequent Nonsustained Ventricular Arrhythmia and No Evidence of Underlying Heart Disease

Abstract

We documented a subclinical but significant increase of left ventricular dimensions that suggests that frequent VPBs may be an initial marker of mild systolic dysfunction of the left ventricle. However, an effect of VPBs per se in modifying left ventricular dimensions cannot be excluded.
