Title (EN) METHOD AND APPARATUS FOR PHRENIC STIMULATION DETECTION
(FR) PROCÉDÉ ET APPAREIL POUR LA DÉTECTION DE STIMULATION PHRÉNIQUE
Abstract:
(EN) Approaches for characterizing a phrenic stimulation threshold, a cardiac capture threshold, a maximum device parameter, and a minimum device parameter are described. A plurality of cardiac pacing pulses can be delivered by using a cardiac pacing device, a pacing parameter of the plurality of cardiac pacing pulses being changed between delivery of at least some of the pulses. One or more sensor signals can be evaluated to detect stimulation of the phrenic nerve by one or more of the plurality of cardiac pacing pluses. The evaluation of the one or more sensor signals and the pacing parameter can be compared to determine if a phrenic stimulation threshold is at least one of higher than a maximum device parameter and lower than a minimum device parameter.
(FR) La présente invention concerne des techniques permettant la caractérisation d'un seuil de stimulation phrénique, d'un seuil de capture cardiaque, d'un paramètre maximal de dispositif, et d'un paramètre minimal de dispositif. Une pluralité d'impulsions de stimulation cardiaque sont administrées à l'aide d'un dispositif de stimulation cardiaque, un paramètre de stimulation de la pluralité d'impulsions de stimulation cardiaque étant modifié entre l'administration d'au moins certaines impulsions. Un signal ou des signaux de capteur peut/peuvent être évalué(s) pour détecter la stimulation du nerf phrénique par une plusieurs de la pluralité d'impulsions de stimulation cardiaque. L'évaluation d'un signal ou de plusieurs signaux de capteur et le paramètre de stimulation peuvent être comparés pour déterminer si le seuil de stimulation phrénique est au moins un seuil supérieur au paramètre maximal de dispositif ou un seuil inférieur au seuil minimal de dispositif.
