In this feasibility study, Laplacian electrocardiograms were utilized to generate body surface moment-of-activation (MOA) maps. The data were obtained with Laplacian sensors from humans. Inverse distance interpolation was applied to improve the image quality. For normal subjects, the MOA maps showed certain common features. A partial activation cycle of atrial ̄utter was mapped and is presented. Further studies must be conducted to determine the diagnostic potential of such patterns based on a larger number of subjects.
