A Common Genetic Variant Risk Score is Associated with Drug-Induced QT Prolongation and Torsade de Pointes Risk: A Pilot Study. [PDF]
, 2017 Background -Drug-induced QT interval prolongation, a risk factor for life-threatening ventricular arrhythmias, is a potential side effect of many marketed and withdrawn medications.

Heritability of Tpeak-Tend interval and T-wave amplitude: a twin study [PDF]
, 2011 Background— Tpeak-Tend interval (TpTe) and T-wave amplitude (Tamp) carry diagnostic and prognostic information regarding cardiac morbidity and mortality. Heart rate and QT interval are known to be heritable traits.

Transient Long QT Development in a Patient with Takotsubo Cardiomyopathy
Journal of Cardiovascular Emergencies, 2016 QT interval prolongation on the electrocardiogram is considered a precursory sign for imminent, potentially lethal ventricular arrhythmias. Beside the inherited condition of long QT syndrome, numerous drugs, certain electrolyte disturbances and early ...

Evaluation of Tp-e interval, Tp-e/QT ratio and Tp-e/QTc ratio in patients with acute pancreatitis
Acta Medica Alanya, 2020 Aim: Acute pancreatitis may affect cardiovascular system regardless of etiology. Electrocardiographic parameters such as QT interval, corrected QT interval (QTc), Tp-e interval and Tp-e/QT, Tp-e/QTc ratio can be used to evaluate myocardial repolarization.

Drink, Drugs, and the QT Interval [PDF]
Clinical Cardiology, 2010 AbstractThe effects of several prescription and illicitly‐used drugs on electrocardiographic repolarization are well documented, most frequently manifested as prolongation of the corrected QT (QTc) interval. The combination of multiple repolarization‐modulating drugs taken in high dosage can occasionally lead to extreme abnormalities of the QTc ...

Measurement and interpretation of electrocardiographic QT intervals in murine hearts. [PDF]
, 2014 Alterations in ECG QT intervals correlate with the risk of potentially fatal arrhythmias, for which transgenic murine hearts are becoming increasingly useful experimental models. However, QT intervals are poorly defined in murine ECGs.

Electrophysiological mechanisms of long and short QT syndromes [PDF]
, 2016 The QT interval on the human electrocardiogram is normally in the order of 450 ms, and reflects the summated durations of action potential (AP) depolarization and repolarization of ventricular myocytes. Both prolongation and shortening in the QT interval

801-4 Prognostic Implications of QT and QU Interval Measures in Acute Myocardial Infarction [PDF]
, 1995 Prolongation of the QT interval corrected using Bazett's formula (QTc) has been reported as a marker for increased risk of arrhythmic events after acute myocardial infarction (AMI). However, the QU interval changes have not been examined.

QTc evaluation in patients with bundle branch block
International Journal of Cardiology: Heart & Vasculature, 2020 Proper measurement of the QT interval on the 12-lead body-surface ECG is challenging in daily practice. Even more difficult is its correct estimation in the presence of repolarization abnormalities, arrhythmias or bundle-branch blocks (BBB).
