May enhance cardiac electrophysiology simulations with membrane heterogeneity; leaves open experimental validation before clinical use.
The EMI model enables detailed, cell-level simulation of cardiac electrical conduction with heterogeneous ion channel distributions, overcoming limitations of classical homogenized models.
Tveito et al. (2017) studied Cardiac electrophysiology. EMI (Extracellular-Membrane-Intracellular) model vs. Classical homogenized models (monodomain and bidomain) was evaluated on Computational complexity and convergence rates. The EMI model successfully simulated collections of cardiac cells with greater modeling flexibility than classical models, and the finite difference method demonstrated optimal computational complexity.
