Cell-to-cell Modelling of the inter-phase between Atrial and Sinoatrial Anisotropic Heterogeneous Nets

AO_SCPCAPBSTRACTC_SCPCAPThe transition between Sinoatrial cells and Atrial cells in the Heart is not fully undefirst ood. Here we focus in cell-to-cell mathematical models involving typical Sinoatrial cells and Atrial cells connected with experimentally observed conductance values exclusively. We are interested mainly in the geometry of the microstructure of the conduction paths in the Sinoatrial Node. We show with some models that appropriate source-sink relationships between Atrial and Sinoatrial cells may occur according to certain geometric arrangements.
