Key result
Optimal experimental design protocols successfully reduced the uncertainty and error in inferred parameters for cardiac electrophysiology models compared to conventional experimental protocols.
Why the study?
Cardiomyocyte action potential models are complex and difficult to parameterise, limiting cellular cardiac models to describing average cell dynamics rather than cell-specific variability.
Optimal experimental design can automatically generate patch-clamp protocols that significantly improve the calibration and parameterization of complex cardiac electrophysiology models compared to traditional protocols.

May improve cardiac model parameterization in research; leaves open clinical translation pending validation.
Lei et al. (2022) studied Cardiac electrophysiology models. Optimal experimental design (OED) vs. Conventional experimental designs was evaluated on Parameter identification accuracy (RMSE of marginal posterior to true values). Optimal experimental design protocols successfully reduced the uncertainty and error in inferred parameters for cardiac electrophysiology models compared to conventional experimental protocols.
