Electrical imaging of cardiac activity

We describe a methodology for a systematic approach to the processing of measurements of electrical potentials which originate in cardiac electrical activity. This methodology can be seen as an imaging modality whose goal is the display and interpretation of an image of the electrical activity of the heart. It requires the display and analysis of electric field data as a function of time and space on complex, irregular three-dimensional geometries. This imaging modality does not reconstruct anatomy, but rather it uses an anatomical model as a basis with which to analyze physical quantities originating in the heart. The goals of this analysis are to achieve a better understanding of normal and abnormal electrical activity of the heart and to apply this knowledge to the diagnosis and monitoring of patients
