(FR) MAPPAGE PHYSIOLOGIQUE POUR L'ARYTHMIE
Abstract
(EN)
A non-transitory computer-readable medium can have instructions executable by a processor. The instructions can include an electrogram reconstruction method to generate reconstructed electrogram signals for each of a multitude of points residing on or near a predetermined cardiac envelope based on geometry data and non-invasively measured body surface electrical signals. The instructions can include a phase calculator to compute phase signals for the multitude of points based on the reconstructed electrogram signals and a visualization engine to generate an output based on the computed phase signals.

La présente invention concerne un support non transitoire lisible par ordinateur pouvant comprendre des instructions exécutables par un processeur. Les instructions peuvent comprendre un procédé de reconstruction d'électrogramme permettant de générer des signaux d'électrogramme reconstruits pour chacun d'une multitude de points se trouvant sur ou à proximité d'une enveloppe cardiaque prédéterminée en se basant sur des données de géométrie et des signaux électriques de surface corporelle mesurés de manière non invasive. Les instructions peuvent comprendre un calculateur de phase permettant de calculer des signaux de phase pour la multitude de points en se basant sur les signaux d'électrogramme reconstruits ainsi qu'un moteur de visualisation permettant de générer une sortie en se basant sur les signaux de phase calculés.
