Patent ID: 6876880

Claim:
A method comprising: detecting an episode of atrial tachycardia in a heart; applying an atrial pacing therapy to the heart in an attempt to terminate the atrial tachycardia; and automatically reapplying the atrial pacing therapy during the non-terminated episode and further comprising: applying at least part of a first sequence of atrial pacing therapies when the atrial rhythm represents atrial tachycardia with a cycle length in a first range; and applying at least part of a second sequence or atrial pacing therapies when the atrial rhythm represents atrial tachycardia with a cycle length in a second range, wherein at least some of the atrial pacing therapies from the first and second sequences are substantially identical; and automatically reapplying the atrial pacing therapy by applying at least one of the substantially identical atrial pacing therapies from the first and second sequences when the cycle length of the atrial rhythm changes between the first range and the second range.
