Predictors of mortality in patients with sustained ventricular tachycardias or ventricular fibrillation and depressed left ventricular function:Importance of β-blockade

To study prognostic factors in patients with sustained ventricular tachycardias (VT) or ventricular fibrillation (VF) complicated by left ventricular dysfunction, we evaluated the predictive value of demographic, clinical, and hemodynamic parameters for cardiac mortality and sudden cardiac death in 85 patients with VT or VF and left ventricular ejection fraction
