Abstract: front page image
(EN)The present invention, in illustrative embodiments, includes methods and devices for analyzing cardiac signals in an implantable cardiac stimulus system. Within the analysis, a threshold may be defined related to a cardiac event rate. If the cardiac event rate does not exceed the threshold, filtering of captured cardiac signals occurs, including attenuating T-waves. If the cardiac event rate does exceed the threshold, circuitry for analog filtering or programming for digital filtering is bypassed to avoid attenuating low frequency components of the captured cardiac signals.
(FR)La présente invention concerne des procédés et des dispositifs conçus pour analyser des signaux cardiaques dans un système de stimulation cardiaque implantable. Lors de l'analyse, un seuil peut être défini en fonction d'un rythme d'événement cardiaque. Si le rythme d'événement cardiaque ne dépasse pas le seuil, des signaux cardiaques capturés sont filtrés et des ondes T sont atténuées. Si le rythme d'événement cardiaque dépasse le seuil, un circuit de filtrage analogique ou une programmation de filtrage analogique est contourné afin d'empêcher une atténuation des composantes à basse fréquence des signaux cardiaques capturés.
