(EN) ESTIMATING RV-TIMINGS FROM LEFT VENTRICULAR (LV) SENSING TIMES FOR ADAPTIVE CARDIAC RESYNCHRONIZATION THERAPY USING DDD/VDD LV PACING WITHOUT A RIGHT VENTRICULAR (RV) LEAD
(FR) ESTIMATION DE TEMPORISATIONS RV À PARTIR DE TEMPS DE DÉTECTION VENTRICULAIRE GAUCHE (LV) POUR THÉRAPIE DE RESYNCHRONISATION CARDIAQUE ADAPTATIVE AU MOYEN D'UNE STIMULATION DDD/VDD LV SANS DÉRIVATION VENTRICULAIRE DROITE (RV)
Abstract
(EN)
Methods and/or devices may be configured to estimate right ventricular- timings from left ventricular (LV) sensing times for adaptive cardiac therapy using DDD/VDD LV pacing without using a right ventricular (RV) lead. One embodiment employs a subcutaneous device (SD) in a patient and a leadless pacing device (LPD) coupled to a patient's heart. Heart activity including atrial and ventricular events are sensed from the patient's heart using the SD. Left ventricular events (LVS) are sensed using the LPD. The SD is used to determine whether cardiac resynchronization pacing therapy (CRT pacing) is appropriate based upon the heart activity sensed by the SD. The SD is further configured to determine timing of CRT pacing pulses for delivery to cardiac tissue through the LPD.

La présente invention concerne des procédés et/ou des dispositifs qui peuvent être configurés pour estimer des temporisations ventriculaires droites à partir de temps de détection ventriculaire gauche (LV) pour une thérapie cardiaque adaptative au moyen d'une stimulation DDD/VDD LV sans utiliser une dérivation ventriculaire droite (RV). Un mode de réalisation utilise un dispositif sous-cutané (SD) chez un patient et un dispositif de stimulation sans dérivation (LPD) couplé au cœur d'un patient. Une activité cardiaque comprenant des événements auriculaires et ventriculaires est détectée à partir du cœur du patient au moyen du SD. Des événements ventriculaires gauches (LVS) sont détectés au moyen du LPD. Le SD est utilisé pour déterminer si une thérapie de stimulation de resynchronisation cardiaque (stimulation CRT) est appropriée sur la base de l'activité cardiaque détectée par le SD. Le SD est en outre configuré pour déterminer la temporisation des impulsions de stimulation CRT pour administration à un tissu cardiaque par l'intermédiaire du LPD.
