This study describes a method to find the torso surface potential based on the boundary element method. In order to find the torso surface potential, the governing equation was developed based on the green's second theorem. The boundary element method (BEM) which has a good computing capability in case of homogeneous and isotropic medium was applied to solve the equation. to validate the BEM, we considered a homogeneous sphere model which has an electrric dopole source inside. The results showed the good agreement between the analytic solution and the computed solution. In normal heart, the simulated torso surface isopotential maps are good agreement with that obtained form the ventricular excitation.
