Direct comparison of a novel antitachycardia pacing algorithm against present methods using virtual patient modeling.

Background: Antitachycardia pacing (ATP) success rates as low as 50% for fast ventricular tachycardias (VTs) have been reported providing an opportunity for improved ATP to decrease shocks.

Objective: The purpose of this study was to determine how a new automated antitachycardia pacing (AATP) therapy would perform compared with traditional burst ATP using computer modeling to conduct a virtual study.

Methods: Virtual patient scenarios were constructed from magnetic resonance imaging and electrophysiological (EP) data.
