摘要

A method and apparatus for maximizing stroke volume through atrioventricular pacing using an implanted cardioverter/pacer accomplishes AV pacing with an AV delay tailored to the particular patient, thereby maximizing accuracy and efficiency. The invention involves the measurement of successive impedance changes, or swings, from one heart cycle to the next, across a pair of electrodes connected in proximity to the heart, the processing of the successive impedance changes to detect variations and directions of variations thereof, the issuance of atrial and ventricular pacing pulses, separated by a time interval therebetween, to the atria and to the ventricles, respectively, and the selective increasing or decreasing of the time interval between the atrial and ventricular pacing pulses in dependence on the directions of variation of the successive impedance changes to maximize impedance swings.
