Yasuo Yamashita (1981) studied this question. Inverse solution using finite element method and generalized inverse matrix regularization was evaluated on Epicardial potential estimation accuracy. An effective regularization method based on the generalized inverse matrix allows estimation of epicardial potentials from body surface maps, requiring about 180 lead points for clinical accuracy.
