Abstract

Recently, it has been shown that medical diagnosis of the human heart may be reduced to searching for the defect positions of the electrical conducting path in the heart. Electrical conducting path searching in the human heart is one of the inverse source problems for which it is difficult to get unique solutions. The authors propose an approach to identifying the electrical conducting paths in the human heart by measuring both the local magnetic and electric fields. It was found that the authors´ method makes it possible to distinguish differences between normal and abnormal human hearts
