Fragmented QRS Complexes Are Associated with Cardiac Fibrosis and Significant Intraventricular Systolic Dyssynchrony in Nonischemic Dilated Cardiomyopathy Patients with a Narrow QRS Interval

Abstract

Fragmentation of QRS complexes on ECG is associated with intraventricular systolic dyssynchrony and subendocardial fibrosis in NDCM patients with a narrow QRS interval and sinus rhythm.
