Title
The effect of conductivity values on ST segment shift in subendocardial ischaemia.
Abstract
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.
