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; 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 wherein the first condition is when a ventricular pacing pulse has not been provided within a first predetermined interval prior to the atrial pacing and the second condition is when a ventricular pacing pulse has been provided within the first predetermined interval prior to the atrial pacing pulse.
