Contains the 3D model used for computational simulation. It is inside a structure with the following fields:

faces: [88376×3 double]        %indices of nodes of triangles of the tetraedhral mesh

    vertices: [336241×3 double]    %3D coordinates of the nodes of the tetraedhral mesh

    tetra: [2017775×4 double] %indices of nodes of each tetraedhral of the tetraedhral mesh

    vertices_surface: [37257×3 double] %3D coordinates of the surface nodes of the tetraedhral mesh

    faces_surface: [74514×3 double] %indices of nodes of surface triangles of the tetraedhral mesh

    ind_surface: [37257×1 double] %indices linking vertices to vertices_surface 

    orienta_vert: [336241×3 double] %fiber direction of each node of the mesh

    Dmat_vert: [336241×1 double] %material of each node of the mesh

File: APs.mat

Simulated transmembrane potential signal for each node of the mesh. 1 second of signal at Fs = 500 Hz

Files: EGM_unipolar_heigh1.mat; EGM_unipolar_heigh0p25.mat

Simulated unipolar EGM signals for 21*21=441 electrograms, for 1 second of signal at Fs = 500 Hz. 

Electrodes were located 1 mm from the atrial wall (EGM_unipolar_heigh1) and 0.25 mm from the atrial wall (EGM_unipolar_heigh0p25)
