QT interval and arrhythmic risk assessment after myocardial infarction

Am J Cardiol. 1999 Jan 15;83(2):266-9, A6. doi: 10.1016/s0002-9149(98)00835-2.


To assess ventricular repolarization features as predictors of ventricular tachyarrhythmias (VT) in patients with previous myocardial infarction, we performed a dynamic study of QT interval from 24-hour electrocardiographic data. QT rate dependence was enhanced in patients with VT when compared with patients without VT.
