1. A method comprising:

  • operating an implantable medical device (IMD) according to a ventricular pacing protocol (VPP) wherein a sensed ventricular event in a first cardiac cycle precludes cardiac pacing in a second cardiac cycle immediately subsequent to the first cardiac cycle;

    initiating a first post atrial ventricular blanking (PAVB) interval following an atrial pacing pulse under a first condition;

    accelerating the first cardiac cycle by delivering a second atrial pacing pulse to terminate the first cardiac cycle early in response to a first sensed indicator; and

    initiating a second PAVB following the atrial pacing pulse under a second condition, wherein the first PAVB is shorter in duration than the second PAVB.
