NON-CONTACT CARDIAC MAPPING, INCLUDING MOVING CATHETER AND MULTI-BEAT INTEGRATION

摘要

PROBLEM TO BE SOLVED: To provide determination and representation of physiological information regarding a heart surface using a non-contact catheter.SOLUTION: A non-contact cardiac mapping method is disclosed that includes: (i) inserting a catheter into a heart cavity having an endocardium surface, the catheter including multiple, spatially distributed electrodes; (ii) measuring signals at the catheter electrodes in response to electrical activity in the heart cavity with the catheter disposed at a distance from the endocardium surface; and (iii) determining physiological information at multiple locations of the endocardium surface on the basis of the measured signals and positions of the electrodes with respect to the endocardium surface. Related systems and computer programs are also disclosed.
