Patent ID: 8046070

Claim:
An implantable pacing device, comprising: pulse generating circuitry for outputting pacing pulses through one or more pre-excitation pacing channels each of which includes an electrode adapted for disposition near a myocardial site; a controller programmed to deliver paces through the pre-excitation pacing channel(s) in accordance with a programmed pre-excitation pacing mode when the device is operating in a pre-excitation state; a switch operable by the controller for configuring the pre-excitation pacing channel(s) with a pacing electrode selected among a plurality of pacing electrodes; a blood pressure sensor communicating with the controller for generating a signal related to a patient's arterial blood pressure, the controller being programmed to derive a blood pressure measurement therefrom; wherein the controller is programmed to optimally configure the pre-excitation pacing channel(s) by sequentially reconfiguring the pre-excitation pacing channel(s) with different pacing electrodes and selecting the pacing electrode for use in the pre-excitation pacing channel(s) that results in the greatest decrease in the blood pressure measurement during delivery of pre-excitation pacing.
