Abstract:
The interaction between the presence of a subendocardial ischemic region and the anisotropic structure of the cardiac muscle is investigated here by means of numerical simulations based on the anisotropic Monodomain and Bidomain models. Extracellular potential distributions during the ST and TQ intervals are computed separately using these nonstationary models. During the ST interval, the extracellular potential patterns differ from those simulated with stationary models used in the literature. These differences are explained by decomposing the cardiac current sources into conormal, axial and orthogonal components and determining which component is dominant during the ST and TQ intervals.
