Changes in left ventricular synchrony and systolic function in dilated cardiomyopathy patients with fragmented QRS complexes

摘要

Fragmented QRS (f-QRS) complexes are associated with adverse cardiovascular events in patients with coronary heart disease; however, the effects on patients with dilated cardiomyopathy (DCM) remain elusive. This study is to investigate the changes of left ventricular (LV) synchrony and systolic function in DCM patients with f-QRS complexes.
