Influence of anatomical definition and substrate condition on simulations of atrial arrhythmias

Dataset from the manuscript "Influence of anatomical definition and substrate condition on simulations of atrial arrhythmias" It contains the 3D model used for the simulations (Model.mat), and several simulations from the manuscript in the corresponding folders (FD_IH, FD_noIH, noDF_IH, noFD_noIH). It also contains an script for visualizing the data (video.m) Model.mat contains the vertex and tetrahedra of the model, as well as the index, vertex and faces of the endocardial and epicadial surface of the model. Simulation data follow this schema: TYPE_dif_NN_remod_MM_S1_XX_YY, where: TYPE: FD/no_D: presence/absence of fiber direction; IH/no_IH: presence/absence of ionic heterogeneities NN indicates the degree of electrical diffusion (in %) MM indicates the degre of electrical remodelling (in %) XX indicates the stimulation point YY indicates the temporal segment of the simulation Each simulation file contains the simulated action potential traces, in a matrix in which rows corresponds to vertex of the model, and columns corresponds to time intervals, at a sample frequency of 500 Hz.
