报告摘要：We study two-dimensional networks of Fitz-High Nagumo oscillators in regimes that mimic cardiac tissue. We include in the networks small layers of cells that have fast recovery characteristics and adjacent layers of cells that have slow recovery. We show that the boundary between the fastand slow cells can initiate fibrillatory-like behavior when activated by a normal excitation wave in the network. We discuss possible connections between these structures and the onset of Atrial Fibrillation, with the goal of improving our understanding and treatment of this costly condition.We use the model to illustrate how increasing heterogeneity in heart tissue can progressively cause first intermittent and then persistent arrhythmic behavior.
