Does time and frequency domain analysis of signal-averaged ECGs predict the inducibility of sustained ventricular tachycardia in patients undergoing electrical programmed stimulation?
A combination of time and frequency domain variables from signal-averaged ECGs can predict the inducibility of sustained ventricular tachycardia with high sensitivity and specificity.
Schramm et al. (1991) studied this question.
