The aim of this study was to investigate the effect of different conductivity values on epicardial surface potential dis- tributions on a slab of cardiac tissue. The study was motivated by the large variation in published bidomain conductivity parameters available in the literature. Simulations presented are based on a previously published bido- main model and solution technique which includes fiber rotation. Three sets of conductivity parameters are considered and an al- ternative set of nondimensional parameters relating the tissue con- ductivities to blood conductivity is introduced. These nondimen- sional parameters are then used to study the relative effect of blood conductivity on the epicardial potential distributions. Each set of conductivity parameters gives rise to a distinct set of epicardial potential distributions, both in terms of morphology and magnitude. Unfortunately, the differences between the poten- tial distributions cannot be explained by simple combinations of the conductivity values or the resulting dimensionless parameters. Index Terms—Anisotropy, bidomain model, conductivity values, simulation, ST depression, subendocardial ischemia. |
