RT Journal Article SR Electronic T1 CELL-TO-CELL MODELING OF THE INTERFACE BETWEEN ATRIAL AND SINOATRIAL ANISOTROPIC HETEROGENEOUS NETS JF bioRxiv FD Cold Spring Harbor Laboratory SP 082529 DO 10.1101/082529 A1 Gabriel López A1 Norma P. Castellanos A1 Rafael Godínez YR 2017 UL http://biorxiv.org/content/early/2017/01/25/082529.abstract AB The 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.
