Patent
CA 2654759
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 spaced from the endocardium surface; and (iii) determining 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. Related systems and computer programs are also disclosed.
L'invention concerne un procédé de cartographie cardiaque sans contact consistant : (i) à introduire un cathéter dans une cavité cardiaque possédant une surface endocarde, le cathéter englobant de multiples électrodes réparties spatialement; (ii) à mesurer des signaux au niveau des électrodes de cathéter en réaction à l'activité électrique dans la cavité cardiaque avec le cathéter espacé de la surface endocarde; et (iii) à déterminer des informations physiologiques en de multiples emplacements de la surface endocarde en fonction des signaux mesurés et des positions des électrodes par rapport à la surface endocarde. L'invention concerne également des systèmes et programmes informatiques associés.
