More Information
Summary:The present invention relates to a system comprising a catheter configured to be inserted into a heart cavity having an endocardium surface, the catheter comprising multiple, spatially distributed electrodes, the multiple electrodes configured to measure signals in response to electrical activity in the heart cavity, and a processing unit configured to determine physiological information at multiple locations of the endocardium surface based on the measured signals and positions of the electrodes with respect to the endocardium surface, and to compute values indicative of a degree of spatial resolution of the determined physiological information for at least some of the locations of the endocardium surface, the degree of spatial resolution being based at least in part on a distance between the catheter electrodes and the endocardium surface.
