摘　　要：以心电位作为求解对象构造心电场的边值问题,它在部分边界上有超定的边值,而在其余的边界上没有边界条件,这与静电场通常的三类边值问题不同。本文给出心电场边值问题有唯一解的一个充要条件。The boundary value problem (BVP) is formulated in terms of epicardial potential for the inverse problem of cardiac electrical field. The BVP is different from the usual three types of BVPs in electrostatic fields because it has over-determined boundary values on one part of the boundary and has no boundary value at all on the other part. This paper gives a necessary and sufficient condition for the uniqueness of epicardial potential, i. e. , the unique solution of the BVP.
