Abstract

Fluorescence imaging of transmembrane potentials is used to observe cardiac activation during fibrillation and defibrillation, but spatial visualization is limited by current techniques. The authors have developed a panoramic cardiac visualization algorithm which reconstructs the geometry of the heart using the fluorescence information as a texture map. This system permits measurement of epicardial electrodynamics over a geometrically realistic representation of the actual heart being studied
