QT and Tpeak-Tend intervals in shift workers

Journal of Electrocardiology, 2013
The present study investigated the relationship between working time and QT and Tpeak-Tend (Tpe) intervals in three shift workers and identified factors associated with the prolongation of these intervals.A total of 60 shift workers underwent a standard 12-lead ECG during the morning, afternoon and night shifts.

Prognostic value of the Tpeak-Tend interval for in-hospital subacute ventricular arrhythmias in tako-tsubo syndrome

Revista Española de Cardiología (English Edition), 2023
The clinical value of electrocardiogram (ECG) repolarization parameters associated with ventricular arrhythmias (VAs) in tako-tsubo syndrome is still under debate. We aimed to evaluate ECG predictors of subacute VAs, defined as those occurring after the first 48hours from admission.This single-center observational study enrolled patients admitted to ...

P wave dispersion, Tpeak–Tend interval, and Tp-e/QT ratio in children with psoriasis

Cardiology in the Young, 2020
AbstractBackground:Psoriasis is a chronic inflammatory, multi-system disease that often begins in childhood and characterised by inflammatory skin, nails, scalp, and joint manifestations. The inflammation in psoriasis may promote some effect on the cardiac conduction system.Objective:The aim of this study is to investigate myocardial repolarisation ...

Prolonged Tpeak-Tend interval is associated with ventricular fibrillation during reperfusion in ST-elevation myocardial infarction

International Journal of Cardiology, 2019
Ventricular fibrillation (VF) during reperfusion in ST-elevation myocardial infarction (STEMI) is associated with increased in-hospital mortality. Dispersion of ventricular repolarization contributes to ventricular vulnerability during ischemia. Tpeak-Tend interval was proposed as a ventricular repolarization dispersion marker, however its value for ...

Duration of electrocardiographic TPEAK-TEND interval in ischemia: Dispersion of repolarization vs. myocardium area at risk

Journal of Electrocardiology
Tpeak-Tend interval (Tpe) is considered to be an ECG reflection of the dispersion of repolarization (DOR), and as such has been proposed as a predictor of arrhythmias. In ischemia, robustness of the Tpe-DOR relationship may suffer from variability of the myocardium at risk (MaR) area.

Tpeak-Tend interval as a new risk factor for arrhythmic event in patient with Brugada syndrome

Journal of Nanjing Medical University, 2007
Abstract Objective To evaluate Tpeak-Tend(Tp-e) interval in surface standard ECG as a new risk factor for arrhythmic event in patient with Brugada syndrome. Methods 23 male patients with Brugada syndrome and 20 male patients with paroxysmal supraventricular tachycardia(PSVT) as the control group were investigated in this study.

Evaluation of Tpeak-Tend interval and Tpeak-end/QT ratio in patients with Sarcoidosis.

Sarcoidosis, vasculitis, and diffuse lung diseases : official journal of WASOG, 2016
rdiogram (ECG), can be used as a marker of transmural dispersion of repolarization. Also, Tp-e/QT and Tp-e/QTc ratios are used as an index of arrhythmogenesis. Prolonged Tp-e interval and Tp-e/QT ratio was found associated with sudden cardiac death in different clinical conditions. Novel ventricular repolarization parameters, Tp-e interval, Tp-e/QT and

Meta-analysis of Tpeak–Tend and Tpeak–Tend/QT ratio for risk stratification in congenital long QT syndrome [PDF]

Journal of Electrocardiology, 2018
Background and objectives: Congenital long QT syndrome (LQTS) predisposes affected individuals to ventricular tachycardia/fibrillation (VF/VF), potentially resulting in sudden cardiac death.
