This chapter presents theoretical methods, the first two of which (the solid angle theorem and the Miller-Geselowitz model) are used to evaluate the electric field in a volume conductor produced by the source — that is, to solve the forward problem. After this discussion follows a presentation of methods used to evaluate the source of the electric field from measurements made outside the source, inside or on the surface of the volume conductor — that is, to solve the inverse problem. These methods are important in designing electrode configurations that optimize the capacity to obtain the desired information. In fact, application of each of the following methods usually results in a particular ECG-lead system.

Keywords:   solid angle theorem, volume conductors, volume source, forward problem, inverse problem, electric field
