Title (EN) SYSTEM AND METHOD FOR ELECTROPHYSIOLOGICAL MAPPING
(FR) SYSTÈME ET PROCÉDÉ DE CARTOGRAPHIE ÉLECTROPHYSIOLOGIQUE
Abstract:
(EN) An electrophysiology map of a portion of a patient's anatomy can be visualized using an electroanatomical mapping system. The system receives a plurality of electrophysiology data points (e.g., an electrophysiology map), which includes a plurality of electrophysiology signals. The system then creates a distribution (e.g., a histogram) for one or more characteristics of the plurality of electrophysiology signals (e.g., dominant cycle length, regular cycle length, peak-to-peak voltage, fractionation, conduction velocity, or the like). The system then analyzes the distribution to determine a display convention (e.g., a range and scale) for a graphical representation of the characteristic based on, for example, a best-fit shape of the distribution, a skew of the distribution, a range of the distribution, and/or a most dominant value of the distribution. The graphical representation can then be output according to the display convention.
(FR) Selon l'invention, une carte électrophysiologique d'une partie de l'anatomie d'un patient peut être visualisée à l'aide d'un système de cartographie électroanatomique. Le système reçoit une pluralité de points de données électrophysiologiques (par exemple, une carte électrophysiologique) comprenant une pluralité de signaux électrophysiologiques. Le système crée ensuite une distribution (par exemple, un histogramme) pour une ou plusieurs caractéristiques de la pluralité de signaux électrophysiologiques (par exemple, longueur de cycle dominant, longueur de cycle régulier, tension de crête à crête, fractionnement, vitesse de conduction, ou similaire). Le système analyse ensuite la distribution pour déterminer une convention d'affichage (par exemple, une plage et une échelle) pour une représentation graphique de la caractéristique basée sur, par exemple, une forme la mieux adaptée de la distribution, une asymétrie de la distribution, une plage de la distribution et/ou une valeur la plus dominante de la distribution. La représentation graphique peut ensuite être présentée selon la convention d'affichage.
