Abstract

Un récupérateur d'énergie convertit en énergie électrique les sollicitations externes appliquées à l'implant au rythme des battements cardiaques. Ce récupérateur comprend un ensemble inertiel et un transducteur délivrant un signal électrique oscillant (S) qui est redressé et régulé pour assurer l'alimentation de l'implant et la recharge d'un organe de stockage d'énergie . Les variations instantanées de ce signal électrique (S) sont analysées dans une fenêtre de détection (W2) suivant ou précédant une contraction ventriculaire (V), de manière à obtenir une information d'activité auriculaire représentative de la contribution (CA1, CA2, CA3) de l'oreillette au signal électrique, notamment une information de présence/absence d'une contraction auriculaire spontanée (As), et/ou des paramètres permettant de déterminer un délai atrioventriculaire (AVD) à appliquer si le ventricule doit être stimulé (Vp).
