title: Nonlinear dynamics in cardiac conduction.
abstract: Electrical conduction in the heart shows many phenomena familiar from nonlinear dynamics.  Among these phenomena are multiple basins of attraction, phase locking, and perhaps period-doubling bifurcations and chaos.  We describe a simple cellular-automation model of electrical conduction which simulates normal conduction patterns in the heart as well as a wide range of disturbances of heart rhythm.  In addition, we review the application of percolation theory to the analysis of the development of complex, self-sustaining conduction patterns.
