Key result
A mixed implicit-explicit numerical scheme for integrating the bidomain model of cardiac action potential propagation was faster than a fully explicit scheme with no increase in algorithmic complexity.
A new mixed implicit-explicit numerical scheme improves the computational efficiency of solving bidomain equations for cardiac action potential propagation.

May accelerate bidomain cardiac simulations; leaves open validation and adoption in research workflows.
Keener et al. (1998) studied Cardiac tissue action potential propagation (computational model). Mixed implicit-explicit numerical scheme vs. Fully explicit scheme was evaluated on Integration speed and algorithmic complexity. A mixed implicit-explicit numerical scheme for integrating the bidomain model of cardiac action potential propagation was faster than a fully explicit scheme with no increase in algorithmic complexity.
