Abstract
Two kinds of chaos can occur in cardiac tissue, chaotic meander of a single intact spiral wave and chaotic spiral wave breakup. We studied these behav iors in a model of two-dimensional cardiac tissue based on the Luo-Rudy I a ction potential model. In the chaotic meander regime, chaos is spatially lo calized to the core of the spiral wave. When persistent spiral wave breakup occurs, there is a transition from local to global spatiotemporal chaos.
