Prolonged Tpeak-to-Tend Interval on the Resting ECG Is Associated With Increased Risk of Sudden Cardiac Death

, 2011
Background— Early studies indicate that prolongation of the interval between the peak and the end of the T wave (Tpeak to Tend [TpTe]) on the 12-lead ECG is a marker of ventricular arrhythmogenesis.

Tpeak–Tend interval predicts arrhythmia recurrence in idiopathic ventricular fibrillation and early repolarization syndrome

Clinical Research in Cardiology
Abstract Background In about 8% of survivors of sudden cardiac death, no structural or electrical heart disease can be identified. Some of these patients with idiopathic ventricular fibrillation (IVF) present ECG markers of early repolarization (Early Repolarization Syndrome, ERS). The T peak–T

Assessment of J-Tpeak interval for prediction of ventricular tachyarrhythmias [PDF]

, 2020
Vzhledem k faktu, že se dnes řadí ischemická choroba srdeční mezi nejčastější příčiny smrti po celém světě, je nesmírně důležité prozkoumávat nové možnosti, jak jí předpovědět, případně zabránit.

association between HERG K897T polymorphism and QT interval in middle-aged finnish women

, 2002
ObjectivesThe aim of this study was to test whether a recently reported polymorphism in the HERG gene coding for the rapidly activating delayed rectifier K+ channel has influence on myocardial repolarization.BackgroundThe length of myocardial ...

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 ...

Tpeak-Tend interval predicts VT inducibility in arrhythmogenic mitral valve prolapse syndrome

Clinical Research in Cardiology
Abstract Background Mitral valve prolapse (MVP) is commonly benign, but an arrhythmic phenotype (AMVP) with increased risk for sudden cardiac death has been described. A prolonged T peak -T end

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.
