“…Usalp et al investigated the length of Tp-e and T wave in cardiac resynchronization therapy. They found that a reduction in the duration of these markers was a significant predictor of a favorable response to the treatment [ 87 ]. Moreover, Banavalikar et al found that Tp-e predicts ventricular tachyarrhythmias in heart failure patients after cardiac resynchronization therapy [ 88 ].…”

Globally, cardiovascular diseases are still the leading cause of death. Numerous methods are used to diagnose cardiovascular pathologies; there is still a place for straightforward and noninvasive techniques, such as electrocardiogram (ECG). Depolarization and repolarization parameters, including QT interval and its derivatives, are well studied. However, the Tpeak‐Tend interval is a novel and promising ECG marker with growing evidence for its potential role in predicting malignant arrhythmias. In this review, we discuss the association between the Tpeak‐Tend interval and several cardiovascular diseases, including long QT syndrome, cardiomyopathies, heart failure, myocardial infarction, and obesity, which constitutes one of the risk factors for cardiovascular diseases.

“…The Tp–e interval is defined as the interval from the peak of the T wave to the end of the T wave. The measurements were performed on lead II and lead V5, and the longest QT and Tp‐e intervals were used for the analyses 17,18 .

Background Patients with coronavirus disease 2019 (COVID‐19) can develop cardiac injury resulting in cardiac arrhythmias, myocarditis, and acute coronary syndrome (ACS). In this study, we aimed to investigate whether COVID‐19 infection affects ventricular repolarization parameters such as Tpeak‐Tend interval (Tp‐e), QT interval, corrected QT (QTc), Tp‐e/QT, and Tp‐e/cQT in patients with ACS. Methods The study consisted of two groups. The first group included patients with ACS and COVID‐19 (Group 1) (n = 50). Polymerase chain reaction test positive patients were enrolled. The second group included patients with only ACS (Group 2) (n = 100). The risk of ventricular arrhythmias was evaluated on the basis of the measured electrocardiographic Tp‐e and QT interval, and QTc, Tp‐e/QT, and Tp‐e/QTc values. Results Tp‐e interval, QTc, and Tp‐e/QTc were significantly higher in the group1 than group 2 (p < .001, p < .018, and p < .001, respectively). Significant positive correlations were found between Tp‐e, D‐dimer level, and C‐reactive protein (CRP) level in the group1 (p = .002, p = 0 .03, and p = .021, respectively). Univariate and multivariate regression analyses revealed that Tp‐e was one of the independent predictor of length of stay in the intensive care unit (ICU). (B = 1.662, p = .006 and B = 1.804, p = .021, respectively). Conclusions In the patients with ACS, COVID‐19 infection caused increases in QTc, Tp‐e, and Tp‐e/QTc ratio. In addition, age and prolonged Tp‐e were found to be independent predictors of prolonged ICU stay.
