Age, gender and drug therapy influences on Tpeak-tend interval and on electrical risk score [PDF]

Journal of Electrocardiology, 2020
Electrical risk score (ERS) has been proposed as easy, inexpensive test to stratify of sudden cardiac death (SCD) risk in subjects with normal left ventricular function. Potentially, aging, gender and drugs can influence ERS affecting two on six electrical markers, particularly, those based on the repolarization.

In vivo comparison of dl-sotalol-induced electrocardiographic responses among halothane anesthesia, isoflurane anesthesia with nitrous oxide, and conscious state

Journal of Pharmacological Sciences, 2021
We compared dl-sotalol-induced electrocardiographic responses in intact dogs using a repeated-measures design among 1% halothane anesthesia, 1.5% isoflurane anesthesia with nitrous oxide (N2O), and conscious state to clarify influences of the anesthetics

The relation between QT interval and T-wave variables in hypertensive patients

Journal of Pharmacy and Bioallied Sciences, 2011
Background : The standard 12-lead ECG (electrocardiogram) continues to be the most frequently recorded noninvasive test in medicine. A prolonged ECG QT interval and Tpeak-Tend (Tpe) interval are predictors of ventricular arrhythmia and sudden cardiac ...

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 ...

The Tpeak – Tend interval as an electrocardiographic risk marker of arrhythmic and mortality outcomes: a systematic review and meta-analysis [PDF]

, 2017
Background: The Tpeak – Tend interval, an electrocardiographic marker reflecting transmural dispersion of repolarization, has been used to predict ventricular tachycardia/fibrillation (VT/VF) and sudden cardiac death (SCD) in different clinical settings.

Postanesthetic torsade de pointes in a patient with unrecognized long QT syndrome -A case report- [PDF]

Korean Journal of Anesthesiology, 2011
Torsade de pointes (TdP) is a devastating form of polymorphic ventricular arrhythmia associated with corrected QT (QTc) interval prolongation. TdP usually terminates spontaneously but frequently recurs and may degenerate to ventricular fibrillation.

Acute and Chronic Changes and Predictive Value of Tpeak-Tend for Ventricular Arrhythmia Risk in Cardiac Resynchronization Therapy Patients

Chinese Medical Journal, 2016
Background: Prolongation of the Tpeak-Tend (TpTe) interval as a measurement of transmural dispersion of repolarization (TDR) is an independent risk factor for chronic heart failure mortality.
