Abstract :
Describes a high-order (cubic Hermite) coupled finite element/boundary element procedure for solving electrocardiographic potential problems to be ultimately used for solving forward and inverse problems on an anatomically accurate human torso. Details of both numerical procedures and the coupling between them are described. Test results, illustrating the accuracy and efficiency of this combination for both two-dimensional (2-D) and three-dimensional (3-D) problems, are also given.
