Electrocardiographic body surface potential mapping.

This article is intended as a review of the field of electrocardiographic body surface potential mapping. The problems associated with measurement of potential distributions will be described, along with the various techniques of data acquisition and display that have evolved over the past decade. Description of mapping applications as they apply to clinical and experimental electrocardiography are presented. The article has been written from a historical perspective, although emphasis is placed on current, state-of-the-art approaches.
