Key result
A lesser ventricular beat-to-beat morphologic variation in ICD recordings predicted successful antitachycardia pacing with an AUC of 0.769 (P<0.0001).

Morphologic variation analysis on ICD electrograms may aid ATP success prediction in VT; hypothesis-generating and requires validation in prospective trials.

Does signal analysis of ventricular tachycardia electrograms predict the response to antitachycardia pacing in patients with ICDs?
Effect estimate: AUC 0.769
p-value: p=<0.0001
Lesser beat-to-beat morphologic variation in ventricular tachycardia electrograms predicts a higher probability of successful antitachycardia pacing in ICD patients.
Tuan et al. (2013) conducted an observational in Ventricular tachycardia in patients with implantable cardioverter-defibrillators (n=20). Ventricular electrogram beat-to-beat morphologic variation (divergence) was evaluated on Successful antitachycardia pacing (ATP) therapy (AUC 0.769, p=<0.0001). A lesser ventricular beat-to-beat morphologic variation in ICD recordings predicted successful antitachycardia pacing with an AUC of 0.769 (P<0.0001).
