This paper reports the development of a simple, inexpensive apparatus that can be constructed and programmed to simulate normal as well as abnormal depolarization and repolarization of the heart and to reproduce an electrocardiogram. The device utilizes a modulated light beam, a series of differential photocells, a patch cord programmer, and a synthesizer consisting of an array of dipoles in a saline conductor. Changes occurring on a cellular level are simulated and programmed and in proper
