Abstract

L'invention concerne un dispositif d'affichage du rythme cardiaque, notamment de type analogique. Ce dispositif comprend des moyens de détection de la partie la plus significative du signal représentant chaque pulsation cardiaque dans un électrocardiogramme, des moyens de filtrage des signaux ainsi détectés à partir de chaque pulsation cardiaque, ces moyens de filtrage présentant une bande passante incluant la fréquence fondamentale des signaux détectés, des moyens de mise en forme des signaux détectés et filtrés, des moyens de conversion fréquence-tension des signaux délivrés par les moyens de mise en forme et des moyens d'affichage de la fréquence, connectés aux moyens de conversion, cette fréquence représentant le rythme cardiaque. Le dispositif est caractérisé en ce que les moyens de filtrage sont constitués par un filtre à bande étroite, commandé par des moyens pour asservir sa fréquence centrale au rythme cardiaque. Application à l'affichage du rythme cardiaque, notamment dans le domaine obstétrical.
