title: A computer model of re-entry in cardiac tissue.
abstract: This paper describes the use of a computer model to investigate the nature of impulse propagation and the mechanisms of electrical instability which precipitate ventricular arrhythmias. The model provides the opportunity for a systematic analysis of the conditions of cardiac conduction under controlled conditions. From the simulation studies performed it is found that the most critical parameter which influences re-entry circuit formation is the ratio of exited to refractory duration.
