Abstract

L'invention porte sur un cardiographe à induction multiple à la surface du corps servant à analyser le type et la fréquence de transmission d'une onde de fibrillation auriculaire notamment le long de la surface du corps, et à analyser/afficher la distribution de la fréquence sur le surface du corps et le résultat de l'identification de la portion d'extrasystole auriculaire. Ledit cardiographe comprend des électrodes fixées au patient, des moyens d'amplification servant à amplifier les signaux cartographiques induits dans les électrodes, des moyens de conversion analogique numérique reliés aux moyens d'amplification et conçus pour la conversion numérique d'un cardiogramme à induction XYZ, une partie d'étalonnage de tension destinée à calibrer la tension du signal venant des moyens de conversion analogique numérique, une partie de stockage dans laquelle le signal venant de la partie d'étalonnage de tension est stocké, une partie arithmétique permettant d'analyser l'onde de fibrillation auriculaire ou l'extrasystole auriculaire au moyen du signal venant de la partie d'étalonnage de tension ainsi que le signal venant de la partie de stockage, et une partie d'affichage servant à afficher la sortie de la partie arithmétique.
