Abstract

La présente invention concerne un système et une méthode de contrôle d'un électrocardiogramme en temps réel, un électrocardiographe de type timbre, et un dispositif de communication. Le système de contrôle d'électrocardiogramme en temps réel comprend un dispositif de mesure d'électrocardiogramme de type timbre fixé à la peau du patient pour mesurer l'électrocardiogramme de ce dernier, créer de premières données d'électrocardiogramme d'un premier format de trame pour transmission sur une courte distance, et transmettre des signaux d'électrocardiogramme issus de cette mesure. Le système comprend également un dispositif de communication de type répéteur pour recevoir lesdites premières données d'électrocardiogramme du dispositif du dispositif de mesure d'électrocardiogramme, extraire les données d'électrocardiogramme, combiner les données d'électrocardiogramme et des informations d'identification du patient afin de créer de secondes données d'électrocardiogramme d'un second format de trame, et transmettre les données créées sur une courte distance. Le système comprend en outre un serveur de contrôle pour recevoir les secondes données d'électrocardiogramme du dispositif de communication de type répéteur, extraire les données d'électrocardiogramme et les informations d'identification du patient, classifier et stocker les données d'électrocardiogramme en fonction des informations d'identification du patient, et fournir ces données en temps réel. Le système comprend enfin un dispositif de stockage pour classifier et stocker les données d'électrocardiogramme. Il peut en outre comprendre un serveur de diffusion pour relayer les données d'électrocardiogramme stockées par le serveur de contrôle vers un lieu éloigné; et un dispositif de visualisation pour visualiser les données d'électrocardiogramme reçues du serveur de diffusion.
