AIMS Mortality in patients with heart failure remains high and is difficult to predict. QT interval parameters on a 12-lead ECG have been shown to predict arrhythmic events in patients with a variety of myocardial diseases. There is some, but not consistent, evidence that QT interval parameters may act as predictors of mortality, in particular sudden death, in patients with heart failure. In an...

background: qt dispersion (qtd) especially after ischemic heart disease and myocardial infarction is a prognostic predictor of mortality, in adult medicine.   objective: this study was undertaken to determine the correlation between qt dispersion and neonatal stress. neonates were divided into 3 groups: normal term (30 cases), normal preterm (30 cases) and sick neonates (36 cases), born between...

Measurement of QT dispersion as calculated from the 12-lead ECG has emerged as a non-invasive assessment for degree of myocardial inhomogeneity. Increased QT dispersion predicts sudden cardiac death in variety of disease states such as acute myocardial infarction and hypertrophic cardiomyopathy. To improve identification of athletes at high risk of sudden death, resting electrocardiograms were ...

Recent studies showed contradictive results of the relation between QT dispersion and the occurrence of ventricular tachyarrhythmias and/or sudden cardiac death. In addition, beta adrenoreceptors blocking agents, which are known to decrease the incidence of lethal arrhythmias after myocardial infarction, administered to the majority of patients in those studies population. Since -blocker as se...

QT interval parameters have been associated with left ventricular hypertrophy (LVH) in hypertensive patients. The aim of this study is to assess this relationship in resistant hypertension and, in particular, to evaluate whether any QT interval parameter could provide additive information for LVH beyond that obtained from the best electrocardiographic voltage criterion. In a cross-sectional stu...

The significance of cardiac autonomic neuropathy (CAN) has not been fully appreciated and there is no unified treatment algorithm. Aim: To investigate the effects benfotiamine (BFT) on corrected QT interval (QTc), dispersion (QTd) spatial QRS-T angle in patients with type 2 diabetes mellitus (T2DM) CAN. 32 T2DM definite stage CAN were allocated to two groups: control (n = 15) received standard ...

BACKGROUND QT interval parameters have been suggested as a predictor of lethal arrhythmia and mortality in patients with myocardial infarction. The aim of the present study was to compare the value of QT interval indices in patients presenting with non-ST-segment elevation myocardial infarction (NSTEMI) between a group of patients with type 2 diabetes mellitus and a nondiabetic group of patient...

BACKGROUND The aim of the study was to evaluate the effect that coronary artery bypass grafting (CABG) and aneurysmectomy in the same session have on QT dispersion (QTd) in moderate or severe left ventricular dysfunction. METHODS Forty-four patients underwent QT interval analyses before and 1 month after aneurysmectomy and CABG. QT interval and QTd were corrected for heart rate using the squa...
