Abstract
A system and method are provided for controlling atrial anti-tachycardia pacing (ATP) delivery based on detection of ventricular pro-arrhythmia during or immediately after atrial ATP. Ventricular pro-arrhythmia is detected based on one or more criteria relating to pro-arrhythmic changes including, but not limited to, ventricular rate changes, R-wave morphology changes, and/or 1:1 or nearly 1:1 atrial-ventricular conduction patterns persisting at high ventricular rates. Upon detecting ventricular pro-arrhythmia, a current atrial ATP sequence is aborted. Atrial ATP therapies may subsequently be temporarily or permanently disabled.
