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).

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 [PDF]

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 ...

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 ...

The Effects of Supraphysiological Estrogen Levels Observed During In Vitro Fertilization Treatment on Cardiac Electrophysiology [PDF]

Annals of Noninvasive Electrocardiology
Supraphysiological estradiol (E2) levels during in vitro fertilization (IVF) may influence cardiac electrophysiology, but this effect is not well defined.

Tpeak-Tend ECG Marker in Obesity and Cardiovascular Diseases: A Comprehensive Review [PDF]

Scientifica
Globally, cardiovascular diseases are still the leading cause of death. Numerous methods are used to diagnose cardiovascular pathologies; there is still a place for straightforward and noninvasive techniques, such as electrocardiogram (ECG ...

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

Europace, 2010
resonance imaging data suggesting right ventricular outflow tract dilatation in patients with Brugada syndrome as the resolution of imaging modalities has improved. 5 This fibrotic process would promote conduction delay in the right ventricle and may explain the presence of a coved ST-segment elevation pattern independent of specific ion channel ...

Heritability of Tpeak-Tend Interval and T-Wave Amplitude [PDF]

Circulation: Cardiovascular Genetics, 2011
Background— Tpeak-Tend interval (TpTe) and T-wave amplitude (Tamp) carry diagnostic and prognostic information regarding cardiac morbidity and mortality. Heart rate and QT interval are known to be heritable traits. The heritability of T-wave morphology parameters such as TpTe and Tamp is unknown. TpTe and Tamp were evaluated in

Short-term repeatability of electrocardiographic Tpeak–Tend and QT intervals

Journal of Electrocardiology, 2014
The electrocardiographic (ECG) Tpeak-Tend interval (TpTe) is associated with arrhythmias and sudden cardiac death. TpTe offers a supplementary measure for the QT interval (QT), yet its repeatability has not been established.

Predictive value of Tpeak-Tend interval of supine and orthostatic electrocardiogram in the diagnosis between psychogenic pseudosyncope and vasovagal syncope in children [PDF]

Scientific Reports
Tpeak-Tend interval (Tp-Te) is an indicator of transmural dispersion of repolarization, which is often related to ventricular arrhythmias. The relationship between Tp-Te and vasovagal syncope (VVS) has been reported in previous studies, but very little ...
