Utility of QT dispersion combined with the signal-averaged electrocardiogram in detecting patients susceptible to ventricular tachyarrhythmia

Am J Cardiol. 1995 Dec 1;76(16):1192-4. doi: 10.1016/s0002-9149(99)80337-3.

Abstract

A simple algorithm that combines QT dispersion with the signal-averaged electrocardiogram QRS duration provides an extremely sensitive method for predicting spontaneous or inducible ventricular tachyarrhythmias. This new algorithm may prove useful in determining which patients are at risk for ventricular tachyarrhythmia.
