Title
(EN) SYSTEM AND METHOD FOR SORTING ELECTROPHYSIOLOGICAL SIGNALS FROM MULTI-DIMENSIONAL CATHETERS
(FR) SYSTÈME ET PROCÉDÉ DE TRI DE SIGNAUX ÉLECTROPHYSIOLOGIQUES PROVENANT DE CATHÉTERS MULTIDIMENSIONNELS
Abstract
(EN)
A plurality of electrophysiological signals measured by a respective plurality of electrodes carried by a multi-dimensional catheter can be sorted relative to a direction of interest, such as a cardiac activation wavefront direction. An electroanatomical mapping system can be used to determine the orientation of the multi-dimensional catheter relative to the direction of interest. For example, the user can manually adjust the orientation by manipulating a slider, a wheel, or a similar graphical user interface control. As another example, the user can draw a presumed orientation on a geometric model. Once the orientation is determined, the system can sort the plurality of electrophysiological signals and output a graphical representation of the sorted plurality of electrophysiological signals, for example as a plurality of traces.
(FR)
Selon la présente invention, une pluralité de signaux électrophysiologiques mesurés par une pluralité respective d'électrodes portées par un cathéter multidimensionnel peuvent être triés relativement à une direction d'intérêt, telle qu'une direction de front d'onde d'activation cardiaque. Un système de cartographie électroanatomique peut être utilisé pour déterminer l'orientation du cathéter multidimensionnel par rapport à la direction d'intérêt. Par exemple, l'utilisateur peut régler manuellement l'orientation en manipulant un curseur, une molette ou un élément de commande d'interface utilisateur graphique similaire. Dans un autre exemple, l'utilisateur peut dessiner une orientation présumée sur un modèle géométrique. Une fois que l'orientation est déterminée, le système peut trier la pluralité de signaux électrophysiologiques et produire une représentation graphique de la pluralité de signaux électrophysiologiques triés, par exemple sous la forme d'une pluralité de tracés.
