Conundrum of the Tpeak‐Tend interval

Journal of Cardiovascular Electrophysiology, 2018
Over the past years, many publications appeared dealing with the clinical utility of the electrocardiographic interval between the peak and the end of the T wave (the Tpe interval). A recently published meta-analysis concluded [1] that the Tpe interval is “a useful risk stratification tool in different diseases and in the general population”.

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.

Increased Tpeak-Tend interval is highly and independently related to arrhythmic events in Brugada syndrome [PDF]

Heart Rhythm, 2015
Risk stratification in Brugada syndrome (BS) remains controversial. The time interval between the peak and the end of the T wave (Tpe interval), a marker of transmural dispersion of repolarization, has been linked to malignant ventricular arrhythmias in various settings but leads to discordant results in BS.We study the correlation of the Tpe interval ...

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

Physiological Reports
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 ...

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

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,

Torsades de Pointes Triggered by Transient Low-Rate Pacing Following Leadless Pacemaker Implantation. [PDF]

J Arrhythm
A case of torsades de pointes triggered by transient bradycardia during Micra AV2 setup highlights a proarrhythmic risk of automated initialization. Individualized programming may be necessary in high‐risk patients with QT prolongation.

The Prognostic Ability of ECG Findings in Predicting Cardiovascular Events: A Five-Year Nested Case-Cohort Study in an Iranian Population (Shiraz Heart Study). [PDF]

Health Sci Rep
ABSTRACT Background and Aims Electrocardiographic (ECG) markers may provide incremental prognostic value for cardiovascular disease (CVD) events beyond traditional ASCVD risk scores. This study aimed to evaluate the association between baseline ECG parameters and the incidence of cardiovascular events over 5 years in a nested case‐control cohort ...

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 ...
