Abstract
Methods and systems for determining optimal spatial resolution for mapping cardiac fibrillation in a patient, including obtaining one or more electrograms, having an initial spatial resolution; calculating at least one electrogram frequency; obtaining one or more electrograms, having a higher spatial resolution; calculating at least one electrogram frequency, having a higher spatial resolution; comparing at least one electrogram frequency having a higher spatial resolution with at least one electrogram frequency having an initial spatial resolution; iterating the steps above until the electrogram frequencies of the two compared electrograms are the same; and identifying at least one of minimum spatial resolution threshold and an optimal spatial resolution based on the step of comparing.
