Impedance Reconstruction of Non-transmural Cardiac Fibrosis

<div>In this dataset we can find geometrical setups that served as an input to carry simulations with openCARP and EIDORS. The setup consists of a Lasso with point electrodes placed on patch of tissue and embedded in a box of blood. The tissue simulates a myocardium that can be either fully healthy, fully scarred, or healthy with a 8-mm width line of scar tissue.</div> <div>In addition, the voltage and local impedance maps obtained as results are included.</div> <div>Two kinds of simulations were performed: reconstruction the forward injection of a 5&micro;A current at 14.6kHz with EIDORS, and the electrical wave propagation with openCARP.</div> <div>For the impedance reconstruction, a four electrode circuit was always used, meaning that two electrodes were part of the injecting pattern and a potential difference was measured between another two. The stimulating pair were sequentially changed among all pairs of neighbouring electrodes, whereas the rest of them contributed to the measurement.</div> <div>The voltage maps were computed taking the recovered EGMs from the electrode positions.</div> <div>&nbsp;</div> <h2>Data structure</h2> <div> <ul> <li>inputGeometries: 24 vtk files representing the input setup for simulations.
