The electromechanical window (EMW) refers to the time interval between aortic valve closure and the end of the T-wave during the same cardiac cycle. Recent studies highlight the role of EMW in assessing the risk of ventricular arrhythmia. This study examines the predictive value of the EMW for ventricular arrhythmias in heart failure with reduced ejection fraction (HFrEF) patients with an implantable cardioverter defibrillator (ICD).
