Abstract

La présente invention concerne des dispositifs de mesure de la période cardiaque et de la hauteur des complexes QRS d'un électrocardiogramme. Ce dispositif reçoit à son entrée S1 un signal d'électrocardiogramme et comprend successivement un filtre adapté 1, un dérivateur 11, un circuit de redressement et de détection de crête 13, et un compteur 17 fournissant un signal numérisé correspondant à la largeurd'un complexe QRS. Application à la surveillance des pathologies cardiaques.
