Evaluation of Tp-Te interval and Tp-Te/QTc ratio in patients with coronary artery ectasia.
AIM Coronary artery ectasia (CAE) is commonly defined as local or generalized dilatation of a coronary vessel up to 1.5 times the diameter of an adjacent vessel. Tp-Te interval and Tp-Te/QT ratio have emerged as novel electrocardiographic markers of increased dispersion of ventricular repolarization. The aim of this study was to evaluate ventricular repolarization by using Tp-Te interval and Tp...
متن کاملProlonged Tp-e Interval, Tp-e/QT Ratio and Tp-e/QTc Ratio in Patients with Type 2 Diabetes Mellitus
BACKGROUND Type 2 diabetes mellitus (T2DM) is associated with increased risk of malignant ventricular arrhythmias. Cardiac electrical inhomogeneity may be the leading cause of the increased arrhythmic risk in patients with T2DM. The peak and the end of the T wave (Tp-e) interval and associated Tp-e/QT ratio are promising measures of ventricular repolarization indicating transmural dispersion of...
متن کاملEffect of Cigarette Smoking on TP-E Interval, TP-E/QT Ratio and TP-E/QTC Ratio
Introduction: Cigarette smoking increases the risk of sudden cardiac death. Smoking may predispose to ventricular fibrillation and sudden cardiac death by altering ventricular repolarization and enhancing sympathetic nervous system activity. We aimed to study the effects of smoking on ventricular repolarization. Methods: We studied 47 healthy subjects. 24 long-term heavy smokers (10 women, mean...
متن کاملEvaluation of Tp-e interval and Tp-e/QT ratio in patients with chronic hepatitis B.
Chronic hepatitis B (CHB) is a chronic inflammatory viral disorder. Several studies have suggested that the interval from the peak to the end of the electrocardiographic T wave (Tp-e) may correspond to the transmural dispersion of repolarisation and that increased Tp-e interval and Tp-e/QT ratio are associated with malignant ventricular arrhythmias. Impaired autonomic function has been describe...
متن کاملEvaluation of Tp-Te Interval and Tp-Te/QT Ratio in Patients with Coronary Slow Flow Tp-Te/QT Ratio and Coronary Slow Flow.
OBJECTIVE Coronary slow flow (CSF) phenomenon is described by angiographically normal coronary arteries with delayed opacification of the distal vasculature. Several studies have suggested that the interval from the peak to the end of the electrocardiographic T wave (Tp-Te) may correspond to the transmural dispersion of the repolarization and that increased Tp-Te interval and Tp-Te/QT ratio are...
