Title
(EN) METHODS AND SYSTEMS FOR MAPPING CARDIAC ACTIVITY
(FR) PROCÉDÉS ET SYSTÈMES DE CARTOGRAPHIE DE L'ACTIVITÉ CARDIAQUE
Abstract
(EN) Cardiac activity can be mapped by receiving an electrogram, transforming the electrogram into the wavelet domain (e.g., using a continuous wavelet transformation) to create a scalogram of the electrogram, computing at least one energy function of the scalogram, and computing at least one metric of the electrogram using the at least one energy function. The metrics of the electrogram can include, without limitation: a QRS activity duration for the electrogram; a near-field component duration for the electrogram; a far-field component duration for the electrogram; a number of multiple components for the electrogram; a slope of a sharpest component of the electrogram; a scalogram width; an energy ratio in the electrogram; and a cycle-length based metric of the electrogram.
(FR) Selon la présente invention, l'activité cardiaque peut être cartographiée par réception d'un électrogramme, transformation de l'électrogramme dans le domaine d'ondelette (par exemple, au moyen d'une transformation en ondelette continue) pour créer un scalogramme de l'électrogramme, calcul d'au moins une fonction d'énergie du scalogramme, et calcul d'au moins une mesure de l'électrogramme à l'aide de la ou des fonctions d'énergie. Les mesures de l'électrogramme peuvent comprendre, sans limitation, une durée d'activité QRS pour l'électrogramme ; une durée de composant de champ proche pour l'électrogramme ; une durée de composant de champ lointain pour l'électrogramme ; un nombre de composants multiples pour l'électrogramme ; une pente d'un composant plus net de l'électrogramme ; une largeur de scalogramme ; un rapport d'énergie dans l'électrogramme ; et une mesure fondée sur la longueur de cycle de l'électrogramme.
