with at least some description of some different
regularization methods too. Findings of comparison with
clinical data from WPW patients were surprising: lower
res model did beter than high res; homogeneous torso
did better than inhomogeneous; simple Tikhonov reg with
energy upper bound was best regularization; and simple
distributions (early in pre-excitation) were better
reconstructed than complex ones (45 msec into the
beat). They have problems getting alignment between
electrodes and nodes on epicardium (derive a special
forward matrix by energizing each element which
encloses an electrode instead of interpolation to the
epicardial nodes)",
