Abstract

This paper proposes one of the novel approaches for human heart diagnosis. Synchronizing with blood pressure pulse, it is possible to measure the electrocardiogram as well as the magnetocardiogram. Taking a gradient of electric potentials of the electrocardiogram yields an electric field vector arrow map. Similarly, taking a rotation of the magnetocardiogram yields an electric current density vector arrow map. Taking a correlation of both maps, it is possible to estimate the electric power density distribution in the human heart. Finite elements (FEM) simulation of this power density distribution shows that the power density distribution corresponds to the electrical conducting path. Thus, it is possible to examine the human heart condition, because most of the human heart problems is caused by the electrical conducting path defect
