Prognostic value of Tpeak-Tend interval in patients with acute pulmonary embolism. [PDF]

BMC Cardiovasc Disord, 2015
Background: The aim of this study was to examine the Tpeak-Tend (Tpe/corrected Tpe) interval, which is an indicator of transmural myocardial repolarization, measured non-invasively via electrocardiogram in patients with acute pulmonary embolism (PE), and

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 ...

Evaluation of ventricular repolarization variables in pediatric COVID-19

Sakarya Tıp Dergisi, 2021
INTRODUCTION: Although the childhood clinic of COVID-19 is more innocent than adults, its unknown aspects continue to cause concern among pediatricians. One of these unsettling aspects is the cardiovascular system effects.

Meta-analysis of Tpeak –Tend and Tpeak –Tend /QT ratio for risk stratification in congenital long QT syndrome [PDF]

, 2018
Background and objectives: Congenital long QT syndrome (LQTS) predisposes affected individuals to ventricular tachycardia/fibrillation (VF/VF), potentially resulting in sudden cardiac death.

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 ...
