1. A cardiac rhythm management device, comprising:
- one or more sensing amplifiers for sensing intrinsic cardiac activity;
one or more pulse generators for delivering pacing pulses to one or more electrodes adapted for disposition near a selected myocardial region;
a controller for controlling the delivery of pacing pulses in accordance with a pacing mode, wherein the controller is programmed to deliver the pacing pulses to the one or more electrodes in a manner that pre-excites the circumscribed region; and
,an impedance sensor for detecting changes in wall motion and wall thickness in an area in proximity to the selected myocardial region and wherein the controller is programmed to modify the delivery of pacing pulses in accordance therewith.
