Figure 13.

Fitting of the MMS model to canine endocardial data of cycle lengths 500 ms and 260 ms. The results of fitting to the voltage data only (blue), fitting to APD data only (orange), and a simultaneous fitting of voltage and APD data minimizing the APD error (green) are shown. The grey lines indicate the APD of the voltage data taken at a voltage value of 0.8. All cases used 1024 particles and 32 iterations of PSO. Four pre-recording stimuli were used in all cases.
