Autonomic nerve activity and the short term variability of Tpeak–Tend interval in dogs with pacing-induced heart failure

BackgroundIn congestive heart failure (CHF), autonomic nervous system (ANS) activity is known to modulate arrhythmic risk through its effects on myocardial repolarization. An increased interval between the peak and the end of T wave (Tpeak–Tend) has been

Heart rate dependency of JT interval sections.

, 2017
BACKGROUND: Little experience exists with the heart rate correction of J-Tpeak and Tpeak-Tend intervals. METHODS: In a population of 176 female and 176 male healthy subjects aged 32.3±9.8 and 33.1±8.4years, respectively, curve-linear and linear ...

ANÁLISIS ELECTROCARDIOGRÁFICO DE LA DISPERSIÓN DEL INTERVALO TPICO-TFINAL EN EL INFARTO AGUDO DE MIOCARDIO CON ELEVACIÓN DEL ST / Electrocardiographic analysis of the T peak-T end interval dispersion in acute myocardial infarction with ST-segment elevation [PDF]

CorSalud, 2010
Resumen Introducción y objetivos: La dispersión del intervalo TPICO-TFINAL (Tpeak-Tend) constituye una novedosa variable electrocardiográfica asociada recientemente, al riesgo de arritmias ventriculares malignas en el síndrome de Brugada, pero apenas se ...

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

, 2015
International audienceRisk 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 ...

The Morphology of the QT Interval Predicts Torsade de Pointes During Acquired Bradyarrhythmias

, 2007
ObjectivesThe purpose of this study was to define the electrocardiographic (ECG) predictors of torsade de pointes (TdP) during acquired bradyarrhythmias.BackgroundComplete atrioventricular block (CAVB) might lead to downregulation of potassium channels ...

The effect of sertindole on QTD and TPTE

, 2010
Recent research suggests that other surrogate markers than QTc, including QTc dispersion and Tpeak-Tend, may better correlate with cardiac arrhythmia risk.

Independent Association of Sudden Cardiac Death and the Tpeak-Tend Interval on Vectorcardiogram

, 2018
The causes of Sudden Cardiac Death (SCD) are still uncertain in the field of electro-cardiology. Cardiac repolarization may be the instance in which fatal arrhythmias lead to SCD development.
