To better understand your simulation, please state which LS-DYNA solvers are involved in the two coupled parts to the problem. Have you employed the implicit mechanical solver on the mechanical side? What is the time step and what controls that time step? I'm not familiar with the electrophysiology side, but I do notice there are multiple hits on dynalook.com when searching for electrophysiology. Perhaps your problem is addressed in one of those papers. Please check.
