Title
(EN) MYOCARDIAL ISCHEMIA MONITOR AND RELATED METHOD
(FR) PROCEDE ET MONITEUR PERMETTANT DE DIAGNOSTIQUER L'ISCHEMIE DU MYOCARDE
Abstract
(EN) An implantable device (30) assists in the diagnosis of myocardial ischemia of a human heart and includes a plurality of electrodes (50-54) and a like plurality of sense amplifiers (72-76) for generating an electrogram for each of the electrodes (50-54). An analog to digital converter (80) reads the voltage magnitudes of the electrogram ST segments which are then stored in a memory (60). An implantable receiver/transmitter (63) is arranged to transmit the magnitudes of the electrogram ST segments to a nonimplanted external receiver.
(FR) Un dispositif implantable (30) permet de diagnostiquer l'ischémie du myocarde d'un c÷ur humain et comprend une pluralité d'électrodes (50-54) et une pluralité identique d'amplificateurs de détection (72-76) pour générer un électrogramme pour chacune des électrodes (50-54). Un convertisseur analogique/numérique (80) lit les intensités de la tension des segments ST des électrogrammes qui sont ensuite stockées dans une mémoire (60). Un récepteur/émetteur implantable (63) est prévu pour transmettre les intensités des segments ST d'électrogramme à un récepteur externe non implanté.
