Patent ID: 7313438

Claim:
A method for delivery of anti-tachycardia pacing (ATP) therapy by a cardiac rhythm management device, comprising: generating electrogram signals from both the right and left ventricles and detecting a sense when the electrogram signal exceeds a specified threshold; detecting a ventricular tachyarrhythmia when a rate at which ventricular senses are detected exceeds a tachyarrhythmia threshold value; measuring an RV-LV interval as the interval between successive right and left ventricular senses and an LV-RV interval as the interval between successive left and right ventricular senses; delivering a burst of one or more ATP pulses in accordance with a selected ATP protocol, wherein the ATP pulses are delivered to the right ventricle if RV-LV interval is less than the LV-RV interval and to the left ventricle if the RV-LV interval is greater than the LV-RV interval.
