Patent ID: 7536223

Claim:
A method for operating a cardiac rhythm management device, comprising: pacing a first ventricle in a first pacing mode in which the first ventricle is paced during a cardiac cycle at a pacing instant defined to occur with respect to expiration of a first escape interval that is reset or stopped by a sense in the contralateral second ventricle; pacing the first ventricle in a second pacing mode in which the first ventricle is paced during a cardiac cycle at a pacing instant defined to occur with respect to expiration of a second escape interval that is reset or stopped by a sense in the contralateral second ventricle; and, during a transition cycle from the first pacing mode to the second pacing mode, inhibiting or delaying a pace to the first ventricle if the pace to the first ventricle would otherwise be delivered within a time interval since a previous pace to the first ventricle which is less than a minimum pacing interval.
