Does an algorithm combining QT dispersion and signal-averaged ECG QRS duration predict spontaneous or inducible ventricular tachyarrhythmias?
An algorithm combining QT dispersion and signal-averaged ECG QRS duration may be a highly sensitive tool for predicting ventricular tachyarrhythmia risk.
Goldner et al. (1995) studied this question.
