Seasonal variations in ventricular repolarization and tachyarrhythmias in hibernating brown bears (Ursus arctos arctos). [PDF]

Physiol Rep
In humans, hypothermia prolongs ventricular repolarization and associates with sustained ventricular tachyarrhythmias. In bears, body temperature drops during hibernation similar to moderate human hypothermia, yet they rarely face fatal outcomes during ...

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.

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

Tpeak-Tend interval and Tpeak-Tend/QT ratio as markers of ventricular tachycardia inducibility in subjects with Brugada ECG phenotype [PDF]

Europace, 2009
The present study investigated whether several ECG markers of ventricular repolarization are associated with ventricular tachycardia/fibrillation (VT/VF) inducibility in subjects with type 1 ECG pattern of Brugada syndrome (BS).The clinical data of 23 individuals (19 males, age 42.69 +/- 14.63) with spontaneous (n = 10) or drug-induced (n = 13) type 1 ...

Prolonged T_peak -T_end interval is a risk factor for sudden cardiac death in adults with congenital heart disease. [PDF]

Congenit Heart Dis, 2019
Objective: Adult congenital heart disease (ACHD) patients are at risk of sudden cardiac death (SCD). However, methods for risk stratification are not yet well-defined. The Tpeak-Tend (TpTe) interval, a measure of dispersion of ventricular repolarization,

Prognostic value of T peak-T end interval on surface ECG in patients undergoing reperfusion therapy for ST segment myocardial infarction

Journal of Indian College of Cardiology, 2023
Background: In post-ST-segment elevation myocardial infarction (STEMI) patients, the indices of repolarization on electrocardiogram (ECG) have shown promise for the prediction of death and malignant arrhythmias.

Evaluation of ventricular repolarization variables in pediatric COVID-19

Sakarya Tıp Dergisi, 2021
INTRODUCTION: Although the childhood clinic of COVID-19 is more innocent than adults, its unknown aspects continue to cause concern among pediatricians. One of these unsettling aspects is the cardiovascular system effects.

Association between Tpeak-Tend interval and QT prolongation: A study of sertindole and sotalol [PDF]

Pharmacology, Drug Development & Therapeutics, 2018
The electrocardiographic interval between the peak and the end of the T-wave (Tpe) is believed to be an arrhythmic risk marker. However, there are also a number of reports that are inconsistent with the usefulness of Tpe for identifying abnormal repolarization. This study was designed to investigate how the Tpe prolongation is correlated to a prolonged
