This chapter considers the response of cardiac muscle to electric stimulation. It considers its particular application to the pacing and defibrillating of the heart. There are a number of significant differences that distinguish cardiac activation from the stimulation of nerve arising in FES. They come about first because of the size differences in these two cases. For stimulation of a nerve the target region is of the order of a few cubic millimeters, while the target region in the heart is in the order of a few cubic centimeters. The chapter describes the various practical aspects of pacemaker design and considers the following topics: control of impulses, site of stimulation, excitation parameters and configuration, implantable energy sources, and electrodes.

Keywords: cardiac pacing; electric stimulation; defibrillation; energy sources; electrodes; cardiac muscle
