1. A system comprising:

  • a ventricular sensing circuit configured to sense ventricular beats;

    a controller, coupled to the ventricular sensing circuit, wherein the controller is configured to obtain V-V intervals between the ventricular beats and to compute a first indicated pacing interval by summing a first addend that includes a most recent V-V interval duration and a second addend that includes a stored previously-computed V-V interval duration;

    a ventricular therapy circuit, coupled to the controller, configured to provide pacing therapy using the first indicated pacing interval; and

    wherein the controller is configured to decrease the first pacing interval following an intrinsic ventricular beat.
