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.

1. A system, comprising:a signal input system including a cardiac signal sensing system adapted to monitor a ventricular signal; and control circuitry coupled to the signal input system, the control circuitry receiving the ventricular signal from the signal input system and including: a trigger event detector adapted to detect a trigger event in the ventricular signal, the trigger event being a series of consecutive ventricular intervals having a short-long-short sequence; and a rate smoothing module activated to provide rate smoothing when the trigger event is detected.
