BACKGROUND Prolonged Tpeak-end (the interval from the peak of the T wave to the end of the T wave) and Tpeak-end/QT ratio have been shown to be markers of arrhythmogenesis in various cardiac disorders. OBJECTIVES The purpose of this study was to evaluate the utility of Tpeak-end and Tpeak-end/QT ratio at admission in patients with acute ST-segment elevation myocardial infarction (STEMI) in predicting malignant ventricular arrhythmias. METHODS The study group included 50 patients presenting… Expand
T Peak-toT End / QT is an Independent Predictor of Early Ventricular Arrhythmias and Arrhythmic Death in Patients with ST Segment Elevation Myocardial Infarction
Background: The interval from the peak to the end of the T wave (Tp-Te) on 12-lead electrocardiogram (ECG) is a measure of transmural dispersion of repolarization; prolonged Tp-Te interval andExpand

TLDR
In patients with aborted arrhythmic SCD, long Tpeak-Tend interval and QTc interval during TH could predict VF development in their follow-up, and the initial VF inducibility was not related with the VFDevelopment in follow- up. Expand
Progressive increase of the Tpeak-Tend interval is associated with ischaemia-induced ventricular fibrillation in a porcine myocardial infarction model
TLDR
Tpeak-Tend prolongation during ischaemia progression predicts VF in the experimental porcine myocardial infarction model and warrants further testing in clinical settings of acute coronary syndromes. Expand
Assessment of the relationship between reperfusion success and T-peak to T-end interval in patients with ST elevation myocardial infarction treated with percutaneous coronary intervention
TLDR
This is the first study that evaluated the relationship between TPE interval and no-reflow defined by STR in patients with STEMI who were treated with pPCI andcTPEPRE and cTPEPOST were found to be independent predictors for incomplete STR. Expand
Prolonged Tpeak-Tend interval is associated with ventricular fibrillation during reperfusion in ST-elevation myocardial infarction.
TLDR
Tpeak-Tend interval before PCI in STEMI was an independent predictor of reperfusion VF in multivariable analysis and warrants further research aimed at prospective validation of Tpeak-tend as a marker of periprocedural arrhythmic risk. Expand
The Tpeak - Tend interval as an electrocardiographic risk marker of arrhythmic and mortality outcomes: A systematic review and meta-analysis.
TLDR
The Tpeak - Tend interval is a useful risk stratification tool in different diseases and in the general population. Expand
Correlation of Prolonged Corrected QT Interval With Ventricular Arrhythmias and In-Hospital Mortality Among ST-Elevation Myocardial Infarction Patients: A Mystique or Lucidity?
TLDR
Prolonged QTc interval is positively correlated with VAs and in-hospital mortality among STEMI patients and there is an utmost need for curation of guidelines that aid in risk stratification and appropriate management of such patients. Expand
T Peak–T End Interval Alteration as Parameter of Successful Fibrinolysis in Patients with ST Segment Elevation Acute Myocardial Infarction
TLDR
There was a greater reduction of Tp-Te interval in STEMI patients with successful fibrinolysis compared to failed fibrinelysis, so it may be used as a alternative parameter of successful fibinolytic therapy. Expand
Association of sleep-disordered breathing and disturbed cardiac repolarization in patients with ST-segment elevation myocardial infarction.
TLDR
It is suggested that sleep-disordered breathing in patients with STEMI may contribute to the risk of developing malignant ventricular arrhythmia, independent of known risk factors. Expand
T-Wave Indices and Atherosclerosis
TLDR
This review provides a comprehensive overview on how Tpeak-Tend is altered in different atherosclerotic conditions such as hypertension, stable coronary artery disease, acute coronary obstruction, and coronary slow flow as well as inflammatory diseases affecting the arterial tree. Expand

TLDR
In patients with STEMI undergoing pPCI, pre-PCI TpTe predicted subsequent all-cause mortality, and the QT interval was increased after the procedure. Expand

TLDR
In patients with left ventricular systolic dysfunction and an implanted ICD, Tpe(c) independently predicts both ventricular tachyarrhythmia and overall mortality. Expand
Prolonged Tpeak-to-Tend Interval on the Resting ECG Is Associated With Increased Risk of Sudden Cardiac Death
TLDR
Prolongation of the TpTe interval measured in lead V5 was independently associated with SCD, with particular utility when the QTc was normal or not measurable because of prolonged QRSD. Expand

Determination of QTD from the surface ECG even when performed with the best available methodology failed to predict subsequent risk in this large series of infarct survivors. Expand
T wave peak-to-end interval and QT dispersion in acquired long QT syndrome: a new index for arrhythmogenicity.
TLDR
Logistic regression analysis revealed that Tpe may be the best predictor for TdP in the QT variables in patients with acquired LQTS, and Cumulative frequency distributions revealed that a Tpe of 0.28 is a good cut-off point for TDP. Expand

TLDR
The combined assessment of T-wave alternans and LP was associated with a high positive predictive value for an arrhythmic event after acute MI, suggesting it could be a useful index to identify patients at high risk of arrhythmmic events. Expand
Dispersion of QT interval in patients with and without susceptibility to ventricular tachyarrhythmias after previous myocardial infarction.
TLDR
It is suggested that the simple, noninvasive measurement of this interval from a standard 12-lead ECG makes a significant contribution to identifying patients at risk for life-threatening arrhythmias after a previous myocardial infarction. Expand

The reliability of automatic measurement of QT, QTp, and TpTe intervals is high but the reproducibility of the repeated measurements ofQT,QTp and TtTe dispersion is comparatively low. Expand
