QT peak prolongation predicts cardiac death following stroke [PDF]
, 2015 Cardiac death has been linked in many populations to prolongation of the QT interval (QTe). However, basic science research suggested that the best estimate of the time point when repolarisation begins is near the T-wave peak.

Effects of atypical antipsychotic drugs on QT interval in patients with mental disorders.
Annals of Translational Medicine, 2018 Background Drug-induced QT prolongation is associated with higher risk of cardiac arrhythmias and cardiovascular mortality. We investigated the effects of atypical antipsychotic drugs on QT interval in children and adults with mental disorders ...

QT Interval Shortening With Isavuconazole: In Vitro and In Vivo Effects on Cardiac Repolarization
Clinical pharmacology and therapy, 2017 The effects of isavuconazole (active moiety of isavuconazonium sulfate) on cardiac ion channels in vitro and cardiac repolarization clinically were assessed in a phase I, randomized, double‐blind study in healthy individuals who received isavuconazole ...

Automated versus Manual Measurement of the QT Interval and Corrected QT Interval [PDF]
Annals of Noninvasive Electrocardiology, 2011 Background: The International Conference on Harmonization E14 Guideline specifies detailed assessment of QT interval or corrected QT interval prolongation when developing new drugs. We recently devised new software to precisely measure the QT interval.

Dynamics of QT Interval in a Patient With Long QT Syndrome and a Normal QT Interval
Japanese Circulation Journal, 1998 A case report of a 15-year-old girl who experienced syncope and torsades de pointes is presented. The girl had a normal QT interval (QTc=0.37 sec) on the resting electrocardiogram (ECG). Infusion of isoproterenol induced QT prolongation (QTc=0.62 sec) and frequent occurrence of multiform ventricular premature beats. Her Holter ECG showed a prolongation
