Abstract
A rate smoothing function used in implantable pulse generators, where detected triggering events cause the rate smoothing function to be activated or deactivated and detected parameter adjusting events cause parameters of the rate smoothing function to be changed. The activation/deactivation and/or change to the parameters of the rate smoothing function are temporary, and the pre-event state of the rate smoothing function is set to a post-adjusting state. In one embodiment, the pre-event state of the rate smoothing function is set to the post-adjusting state after a first time interval.

- monitoring for one or more triggering events;
- wherein one of the triggering events is a short-long-short cycle length sequence of ventricular intervals;
- and
- when a triggering event is detected, activating a rate smoothing system.
