1. A method of delivering pacing therapy to a heart, comprising:

  • adjusting, for each cardiac cycle of a plurality of cardiac cycles, one or both of an atrioventricular (A-V) timing interval and an atrial (A-A) timing interval to oppose beat-to-beat ventricular (V-V) variability so as to maintain relatively constant V-V intervals between ventricular beats of different cardiac cycles over the plurality of cardiac cycles; and

    delivering the pacing therapy using the adjusted timing intervals.
