Abstract: A medical device is configured to identify a first group of cardiac events, determine a cardiac event interval based on the first group of cardiac events and determine whether the cardiac event interval is less than a threshold interval or greater than the threshold interval. The medical device is configured to select a first blanking period duration if the cardiac event interval is less than the threshold interval or a second blanking period duration if the cardiac event interval is greater than the threshold interval.

Abstract: A medical device is configured to determine a rate smoothing pacing interval based on at a ventricular cycle length ending with a ventricular pacing pulse and determine a post-sense ventricular pacing interval based on a ventricular cycle length ending with a sensed ventricular event signal. The medical device may be configured to start a ventricular pacing interval set to the post-sense ventricular pacing interval in response to the sensed ventricular event signal and generate a ventricular pacing pulse in response to the expiration of the post-sense ventricular pacing interval.
