May accelerate atrial simulations for research; leaves open clinical translation pending human validation.
A systematically reduced atrial myocyte model accurately reproduces key electrophysiological properties while significantly decreasing computational time, facilitating patient-specific modeling.
Lombardo et al. (2017) studied Cardiac arrhythmias. Manifold boundary approximation method for model reduction vs. Original detailed model of Koivumaki et al. was evaluated on Action potential shape, restitution curve, and simulation time. Systematic reduction of the Koivumaki atrial myocyte model from 42 to 11 variables decreased simulation times more than three-fold while accurately reproducing action potential shape.
