Ventricular repolarization measurement by QTc interval and QT dispersion can recognize high-risk patients. Previous research tended to evaluate the act of indicators alone but this study aimed elucidate their prognostic utility before after modifying confounding parameters in risk stratification different aspects prognosis decompensated heart failure patients with systolic dysfunction.Data 98 variables were evaluated determine predictive value concerning arrhythmic events, in-hospital, long-term mortality.From 858 cases that presented acute failure, 19.2% (n=165) enrolled study. During hospitalization, events cardiac-related mortality occurred 56(33.9%) 11(7%) patients, respectively. independent predictors arrhythmia in-hospital adjustment (arrhythmic events: OR 1.085, P=0.007, 1.077, mortality: 1.116, P=0.009, 1.067, P=0.011). After being discharged, they tracked for 181±56 days. Within 16 deaths follow-up time, 6 sudden cardiac documented. Cox regression, defined as predictor all-cause death (all-cause: HR 1.041, 95% CI 1.015-1.067, P=0.002; death: 1.063, 1.023-1.105, P=0.002); nevertheless, efforts demonstrate failed.The nature was significant modification variables; therefore, should be measured ventricular
