BACKGROUND:
Ventricular arrhythmia, ischemic left ventricular dysfunction
VENTRICULAR ARRHYTHMIA, VENTRICULAR ARRHYTHMIA
Ventricular arrhythmia is an important cause of mortality in patients with ischemic left ventricular dysfunction. Revascularization with coronary artery bypass graft or percutaneous coronary intervention is often recommended for these patients before implantation of a cardiac defibrillator because it is assumed that this may reduce the incidence of fatal and potentially fatal ventricular arrhythmias, although this premise has not been evaluated in a randomized trial to date.
