Patent ID: 8738131

Claim:
An apparatus for LV (Left Ventricular) pacing stimulus delivery resulting in augmented stroke volume, comprising: transducing means for measuring movement of a portion of the lateral wall of a LV and providing a movement signal related to such movement; a movement measurement circuit operatively coupled to the transducing means; a pulse generator coupled to the measurement circuit; a left pacing electrode in electrical communication with a portion of the LV and electrically coupled to a post extrasystolic potentiation (PESP) pacing circuit of the pulse generator; an LV movement threshold circuit coupled to the transducing means and responsive to the movement signal and adapted to generate a signal indicating a successful post extrasystolic depolarization LV pacing parameter; and a programmable circuit coupled to the threshold circuit and the pulse generator and programmed to modify LV pacing parameters until the signal indicative of a successful PESP LV pacing parameter is generated by the threshold circuit.
