Comparison of different regularization methods estimates endocardial potentials from noncontact probes, indicating superior accuracy with higher order techniques.
In this paper we compare zero and first order Tikhonov and Generalized Eigensystem (GES) regularization for estimating the endocardial potentials from measured potentials on a noncontact probe. In all cases, the Composite Residual Error and Smoothing Operator (CRESO) was used to estimate the regularization parameter In this limited study the use of higher order regularization produced larger average correlation coefficients between the estimated and measured endocardial electrograms.
