  • Method of and apparatus for generating a model of a cardiac surface having a plurality of images representing electrogram voltages
    Patent number: 8838216
    Abstract: A method of generating a model of a cardiac surface having a plurality of images representing electrogram voltages for a plurality of measured points within a heart comprises measuring an electrogram voltage at a plurality of points within a heart, generating a first model of a cardiac surface of the heart, generating an image representing each electrogram voltage, each image having a characteristic representative of the electrogram voltage, and generating a further model of a cardiac surface. The images representing the electrogram voltages protrude from the further model of the cardiac surface at points on the further model corresponding to the points at which the electrogram voltages were measured. There is also disclosed an apparatus for generating a model of a cardiac surface.
