Patent ID: 6885890

Claim:
A method for operating a cardiac rhythm management device, comprising: detecting senses from multiple ventricular sites, where a sense corresponds to an intrinsic depolarization occurring at the site; detecting a ventricular tachycardia when a time interval between successive senses detected from one of the sites meets a specified rate criterion; pacing one of the sites designated as the primary anti-tachycardia pacing (ATP) site with an anti-tachycardia pacing sequence in accordance with an ATP protocol when a ventricular tachycardia is detected, wherein the sequence is delivered at a selected coupling interval with respect to detection of a sense at the primary ATP site; pacing one or more of the other sites, designated as secondary ATP sites, at a selected ATP offset interval with respect to a pace delivered to the primary ATP site in the anti-tachycardia pacing sequence; and, reverting to a ventricular resynchronization paging mode when the ventricular tachycardia is terminated, wherein in the resynchronization mode one of the sites is designated as the rate site and paced with a bradycardia pacing mode and one or more of the other sites are paced at specified resynchronization offset intervals with respect to paces delivered to the rate site.
