(A.i) True epicardial potentials of ST elevated MI (model 1) at the diseased node (vertical dotted line: time stamp at t = 85ms), (B.i) True heart potentials of T elevated case from model 1 (vertical dotted line: time stamp at t = 125 ms). Results of the epicardial estimations obtained from inverse algorithms on the model 2 with respect to time for both the cases (A,B): (ii) standard Tikhonov regularization, (iii) Bayesian modeling with Gaussian priors and (iv) variational Bayesian inference in noise free conditions, and reconstructions from (v) Tikhonov regularization, (vi) Bayesian modeling, and (vii) Variational Bayesian inference method for 8 dB SNR, respectively.
