Abstract

A brief history of body surface potential mapping (BSPM), which is a series of ECGs at various positions on a body surface, is given, and its features are described. Among the problems that must be solved if the BSPM is to be used as a routine clinical tool is the need to reduce the number of leads without losing the spatiotemporal information. To determine the theoretical lead arrangement and the minimum number of leads, the local spatial potential changes of BSPM are analyzed using the Wigner distribution, which has good space-frequency resolution. A method for reducing the number of redundant leads and a method for reconstructing the BSPM from the optimum leads are given.<>
