1. A cardiac device, comprising:

  • one or more ventricular pacing channels for delivering pacing pulses to one or more ventricular sites;

    a controller programmed to operate the device in either a normal operating mode or AV delay reduction (AVDR) mode;

    wherein, in the AVDR mode, the controller is programmed to deliver paces to the one or more ventricular sites using a pacing mode that decreases atrial preloading of the ventricles as compared with the normal operating mode; and

    ,wherein the controller is programmed to intermittently switch from the normal operating mode to the AVDR mode according to a one or more specified entry conditions and switch from the AVDR mode to the normal operating mode according to one or more specified exit conditions.
