Abstract

L'INVENTION CONCERNE UN STIMULATEUR CARDIAQUE REAGISSANT A L'ACTIVITE DU COEUR. IL COMPORTE UN AMPLIFICATEUR DE DETECTION D'ACTIVITE CARDIAQUE A ENTREE DIFFERENTIELLE ET DONT LA REPONSE EST INDEPENDANTE DE LA POLARITE DES SIGNAUX DETECTES, ET UN CIRCUIT DE VALEUR ABSOLUE QUI PRODUIT DES SIGNAUX DE MEME POLARITE REPRESENTANT LES SIGNAUX D'UNE POLARITE OU L'AUTRE QUI ONT ETE DETECTES. L'INVENTION S'APPLIQUE NOTAMMENT A DES STIMULATEURS CARDIAQUES NUMERIQUES.
