Electrocardiographic T-wave parameters in families with long QT syndrome.
Markiewicz-Łoskot G, Moric-Janiszewska E, Mazurek B, Łoskot M, Bartusek M, Skierska A, Szydłowski L. Markiewicz-Łoskot G, et al. Adv Clin Exp Med. 2018 Apr;27(4):501-507. doi: 10.17219/acem/68441. Adv Clin Exp Med. 2018. PMID: 29616748 Free article.
BACKGROUND: T-wave parameters, especially the Tpeak-Tend interval (TpTe), reflect the total dispersion of repolarization, whose amplification may lead to the development of life-threatening ventricular arrhythmias observed in the long QT syndrome (LQTS …

T(peak)T(end) interval in long QT syndrome.
Kanters JK, Haarmark C, Vedel-Larsen E, Andersen MP, Graff C, Struijk JJ, Thomsen PE, Christiansen M, Jensen HK, Toft E. Kanters JK, et al. J Electrocardiol. 2008 Nov-Dec;41(6):603-8. doi: 10.1016/j.jelectrocard.2008.07.024. Epub 2008 Sep 25. J Electrocardiol. 2008. PMID: 18822425
BACKGROUND: The T(peak)T(end) (T(p)T(e)) interval is believed to reflect the transmural dispersion of repolarization. Accordingly, it should be a risk factor in long QT syndrome (LQTS). The aim of the study was to determine the effect of genotype on T(p)T(e) …

Drug-induced spatial dispersion of repolarization.
Antzelevitch C. Antzelevitch C. Cardiol J. 2008;15(2):100-21. Cardiol J. 2008. PMID: 18651395 Free PMC article. Review.
Amplification of this spatial dispersion of repolarization (SDR) underlies the development of life-threatening ventricular arrhythmias associated with inherited or acquired ion channelopathies giving rise to the long QT, short QT and Brugada syndromes (BrS). …

Carbon monoxide poisoning increases Tpeak-Tend dispersion and QTc dispersion.
Eroglu M, Uz O, Isilak Z, Yalcin M, Yildirim AO, Kardesoglu E. Eroglu M, et al. Cardiovasc J Afr. 2014 May-Jun;25(3):106-9. doi: 10.5830/CVJA-2014-012. Cardiovasc J Afr. 2014. PMID: 25000439 Free PMC article.
Also, carboxyhaemoglobin (COHb) levels were recorded in group 1. Tpeak-Tend (TpTe) interval, TpTe dispersion, TpTe/QT ratio, QT interval and QTd durations were measured as parameters of ventricular repolarisation. ...No statistically significant …

Improved Clinical Risk Stratification in Patients with Long QT Syndrome? Novel Insights from Multi-Channel ECGs.
Samol A, Gönes M, Zumhagen S, Bruns HJ, Paul M, Vahlhaus C, Waltenberger J, Schulze-Bahr E, Eckardt L, Mönnig G. Samol A, et al. PLoS One. 2016 Jul 5;11(7):e0158085. doi: 10.1371/journal.pone.0158085. eCollection 2016. PLoS One. 2016. PMID: 27379800 Free PMC article.
BACKGROUND: We investigated whether multichannel ECG-recordings are useful to risk-stratify patients with congenital long-QT syndrome (LQTS) for risk of sudden cardiac death under optimized medical treatment. ...CE was associated with a longer QTc-interval (5 …

Prolongation of this interval predisposes to life-threatening ventricular arrhythmias in long QT syndrome, polymorphic catecholaminergic ventricular tachycardia, Brugada syndrome and short QT syndrome and may be an indicator of increased …

The pattern of Tpeak-Tend and QT interval, and J wave during therapeutic hypothermia.
Kim SM, Hwang GS, Park JS, Shin JS, Kim GW, Yang HM, Choi SY, Yoon MH, Shin JH, Tahk SJ. Kim SM, et al. J Electrocardiol. 2014 Jan-Feb;47(1):84-92. doi: 10.1016/j.jelectrocard.2013.05.139. Epub 2013 Jun 27. J Electrocardiol. 2014. PMID: 23809915 Clinical Trial.
METHODS: We measured the QTc and the interval from the peak to the end of the T wave (TpTe) from the V4 and V6 leads in 20 patients with TH. The TpTe was also expressed as a ratio to the duration of QT ([TpTe/QT]100%), and to the corrected value …

The effect of sertindole on QTD and TPTE.
Nielsen J, Andersen MP, Graff C, Kanters JK, Hardahl T, Dybbro J, Struijk JJ, Meyer JM, Toft E. Nielsen J, et al. Acta Psychiatr Scand. 2010 May;121(5):385-8. doi: 10.1111/j.1600-0447.2009.01534.x. Epub 2010 Jan 19. Acta Psychiatr Scand. 2010. PMID: 20085555
METHOD: Digital 12-lead ECG was recorded at baseline and at steady-state in 37 patients switched to sertindole. ECG was analysed for Fridericia-corrected QT duration (QTcF), QT dispersion and Tpeak-Tend. RESULTS: From a baseline QTcF of 407 +/- 22 ms, mean QTcF prol …
