Abstract:
1. A cardiac rhythm management device, comprising: one or more pulse generators to connecting to a plurality of pacing channels in order to deliver electrical stimulation to a plurality of ventricular sites; a controller programmed to operate the device in either a normal operating mode or a high-energy stimulation mode; wherein the controller is programmed to periodically switch from the normal operating mode to the high-energy stimulation mode according to a defined schedule; wherein, in the normal operating mode, the controller is programmed to deliver pacing pulses in accordance with a right ventricle-only pacing mode; and, wherein, in the high-energy stimulation mode, the controller is programmed to deliver pacing pulses to a left ventricular site at an energy higher than the energy of the pacing pulses delivered in the normal operating mode.
