A mathematical procedure for solving the inverse potential problem of electrocardiography. analysis of the time-space accuracy from in vitro experimental data

摘要: Abstract The inverse potential problem of electrocardiography leads to a Cauchy for an elliptic operator and is strongly ill posed. Its solution must be determined by some regularization technique in which parameter controls the amount solution. Therefore choice this smoothing important achieving best accuracy attainable given discrete approximation errors noise level on data. A regularized procedure applied data from vitro experiment, new criterion quasi-optimal value described. performance investigated, detailed analysis results carried out. This concerns both recovered epicardial maps (space analysis) ECGs (time analysis).
