Abstract

Le système selon l'invention est prévu pour être utilisé par des patients présentant des problèmes cardiaques ou appliqué à ces derniers. Ce système permet également de contrôler ou d'assurer le suivi de ces patients. Selon ce système, un spécialiste ou un cardiologue peut ainsi traiter ou conseiller à distance ses patients, en particulier en cas de risque d'infarctus. Le système selon l'invention utilise les moyens de communication par satellite, par l'intermédiaire des raiseaux INMASART et consiste à placer sur le patient une unité de répétition portative, connectée à un système téléphonique auxiliaire remplissant la fonction d'un radio-émetteur avec modem. Ce dernier transmet en continu le signal ECG (électrocardiogramme) au PC de l'unité de répétition, et les informations sont traitées par l'ordinateur en fonction de la pathologie du patient. Ce système assure une communication entre ce dernier et une station placée à distance dans laquelle se situe le spécialiste qui peut ainsi transmettre directement des informations et des données à son patient.
