Abstract
The cardiac output of a paced heart is optimized by measuring a parameter indicative of the volume of blood in a heart chamber as a function of a pacing parameter. The pacing parameter is adjusted so that the heart pumps the maximum volume at different rates for hearts with debilitating pathologies. This pacing parameter is then used for controlling the pacing pulses for pacing the heart. Preferably the volume parameter is the paced depolarization integral and the pacing parameter is the A-V delay.
