Abstract
A new approach is described to improve the spatial resolution of body surface mapping of cardiac electrical activity by measuring the surface Laplacian of the body surface potential. A high resolution body surface Laplacian mapping system has been developed and successfully applied to study the Laplacian maps of normal human subjects. Both simulation and experimental studies have shown that the body surface Laplacian mapping provides much better spatial resolution than potential mapping. This may enable Laplacian mapping to identify from the body surface spatially separated myocardial events, and to play a significant role in quantitative cardiac electrophysiology.
