ABSTRACT:
An implantable pacemaker maintains a prescribed relationship between stimulation pulse amplitude and pulse width so as to provide an adequate safety factor above a stimulation threshold, while minimizing the current drain on the pacemaker battery. A series of stimulation pulse energies, each realized with a prescribed pulse amplitude and pulse width pair, are determined that may be used by the pacemaker as operating points. These operating points are numbered in order of increasing energy, and all adjustments of the pacing energy are made by selecting one of these operating points.
