Abstract

Système portatif de faibles dimensions et procédé de protection cardiaque. Un dispositif d'enregistrement du type électrocardiogramme est monté sur un collier possédant un pendentif pour l'échantillonnage et le stockage à tout moment de signaux d'électrocardiogramme, et pour la production d'indications quant à la normalité ou l'anormalité des signaux d'électrocardiogramme après analyse de ceux-ci. Le système comporte également un dispositif de transmission des signaux stockés dans le dispositif d'enregistrement, et un dispositif d'analyse automatique des signaux d'électrocardiogramme en vue de fournir des analyses de ceux-ci et, le cas échéant, différents index. Le système permet de capter des signaux d'électrocardiogramme chez un malade lorsque celui-ci a une crise cardiaque, et de restituer ces signaux à l'instant voulu.
