Title (EN) AUTOMATIC DETERMINATION AND SELECTION OF FILTERING IN A CARDIAC RHYTHM MANAGEMENT DEVICE
(FR) DÉTERMINATION ET SÉLECTION AUTOMATIQUES DE LA FILTRATION DANS UN DISPOSITIF DE GESTION DU RYTHME CARDIAQUE
Abstract:
(EN) Methods and/or device facilitating and selecting among multiple modes of filtering a cardiac electrical signal, in which one filtering mode includes additional high pass filtering of low frequency signals, relative to the other filtering mode. The selection filtering modes may include comparing sensed signal amplitude to one or more thresholds, using the multiple modes of filtering. In another example, an additional high pass filter is enabled, over and above a default or baseline filtering mode, and the detected cardiac signal is monitored for indications of possible undersensing, and/or for drops in amplitude toward a threshold, and the additional high pass filter may be disabled upon finding of possible undersensing or drop in signal amplitude.
(FR) La présente invention concerne des procédés et/ou un dispositif facilitant et sélectionnant parmi de multiple modes de filtration un signal électrique cardiaque, dans lequel un mode de filtration comprend la filtration passe-haut supplémentaire de signaux de basse fréquence, par rapport à l’autre mode de filtration. La sélection des modes de filtration peut comprendre la comparaison de l’amplitude d’un signal détecté à un ou plusieurs seuils, en utilisant les modes multiple de filtration. Dans un autre exemple, un filtre passe-haut additionnel est activé, sur et au-dessus d’un mode de filtration par défaut ou de référence, et le signal cardiaque détecté est surveillé concernant les indications d’une sous-détection possible, et/ou de chutes d’amplitude vers un seuil, et le filtre passe-haut additionnel peut être désactivé en cas de découverte d’une sous-détection ou d’une chute possibles d’amplitude du signal.
