Adding Defibrillation Therapy to Cardiac Resynchronization on the Basis of the Myocardial Substrate
BACKGROUND: Patients with nonischemic dilated cardiomyopathy (DCM) may be at lower risk for ventricular arrhythmias compared with those with ischemic cardiomyopathy (ICM). In addition, DCM has been identified as a predictor of positive response to cardiac resynchronization therapy (CRT).OBJECTIVES: The aim of this study was to investigate the impact of an additional implantable cardioverter-defibr
