Tpeak‐Tend, Tpeak‐Tend/QT ratio and Tpeak‐Tend dispersion for risk stratification in Brugada Syndrome: A systematic review and meta‐analysis [PDF]

Journal of Arrhythmia, 2018
Background Brugada syndrome is an ion channelopathy that predisposes affected subjects to ventricular tachycardia/fibrillation (VT/VF), potentially leading to sudden cardiac death (SCD).

Increase in Tpeak–Tend interval induced by cardiac resynchronization therapy is a predictor of ventricular tachyarrhythmia

Journal of Arrhythmia, 2012
Background: The impact of cardiac resynchronization therapy (CRT) on dispersion of repolarization is controversial. This study aimed to determine whether CRT alters the QT interval and Tpeak–Tend interval (Tpeak–end) and whether such changes relate to ...

Predictive Value of Tpeak – Tend Indices for Adverse Outcomes in Acquired QT Prolongation: A Meta-Analysis [PDF]

Frontiers in Physiology, 2018
Background: Acquired QT interval prolongation has been linked with malignant ventricular arrhythmias, such as torsade de pointes, in turn predisposing to sudden cardiac death. Increased dispersion of repolarization has been identified as a pro-arrhythmic

The relationship between the TSH values and the Tpeak – Tend interval duration in hypothyroid patients receiving Levothyroxine treatment

Romanian Journal of Internal Medicine, 2019
Introduction. Changes in thyroid hormone level can affect the cardiovascular system. The aim of this study was to show how the Tpeak -Tend (Tpe) interval, which is a new marker of ventricular arrythmia, is affected in patients who have become euthyroid ...

Automated Algorithm for J-Tpeak and Tpeak-Tend Assessment of Drug-Induced Proarrhythmia Risk. [PDF]

PLoS ONE, 2016
Prolongation of the heart rate corrected QT (QTc) interval is a sensitive marker of torsade de pointes risk; however it is not specific as QTc prolonging drugs that block inward currents are often not associated with torsade.

A Longer T_peak-T_end Interval Is Associated with a Higher Risk of Death: A Meta-Analysis. [PDF]

J Clin Med, 2023
A noninvasive tool for cardiovascular risk stratification has not yet been established in the clinical routine analysis. Previous studies suggest a prolonged Tpeak-Tend interval (the interval from the peak to the end of the T-wave) to be predictive of ...

Tpeak-Tend Interval during Pregnancy and Postpartum. [PDF]

Int J Environ Res Public Health, 2022
Background: Pregnancy is a condition in which new cardiac arrhythmias can occur or prior undiagnosed arrhythmias may provide symptoms. The occurrence of severe ventricular arrhythmias and polymorphic ventricular tachycardia that may lead to fainting or ...

Association between the Tpeak‐Tend interval on admission and coronary microvascular dysfunction in Takotsubo syndrome

ESC Heart Failure
Aims The Tpeak‐Tend interval on electrocardiogram may be a predictor of worse outcomes in Takotsubo syndrome (TTS), but the mechanisms have not been fully determined. This study aimed to investigate the relationships between the corrected Tpeak‐Tend (cTp‐

Early Repolarization, Fragmented QRS and Tpeak-Tend Interval as Electrocardiographic Markers in Patients with Idiopathic Ventricular Arrhythmias: a Brief Review

Journal of Cardiac Arrhythmias, 2020
Introduction: Idiopathic ventricular tachycardia and ventricular fibrillation, as causes of sudden cardiac death, are entities with mechanisms poorly studied and understood to date. The electrocardiogram (ECG) is a simple tool, but with great diagnostic

Sex and race differences in J-Tend, J-Tpeak, and Tpeak-Tend intervals [PDF]

Scientific Reports, 2019
To facilitate the precision of clinical electrocardiographic studies of J-to-Tpeak (JTp) and Tpeak-to-Tend (Tpe) intervals, the study investigated their differences between healthy females and males, and between subjects of African and Caucasian origin ...
