Abstract

L'invention concerne un dispositif multifonctionnel portable servant à mesurer un électrocardiogramme et capable de corriger un signal d'entrée, ainsi qu'un procédé de correction de signal. Ce dispositif comprend un capteur à électrodes, un pré-ASP et un ASP. Le capteur capte des signaux d'entrée provenant d'au moins trois fils conducteurs reliés au corps du patient. Le pré-ASP sélectionne un trajet pour un signal capté par le capteur, en réponse à une pluralité de signaux de contrôle de sélection. Le ASP élimine le bruit contenu dans le signal capté depuis le pré-ASP et l'amplifie. L'invention concerne également un procédé de correction de signal servant à corriger un signal d'entrée (dans la mesure où ce signal contient une erreur) dans un dispositif portable de mesure d'électrocardiogramme. Ce procédé consiste à: déterminer une erreur dans trois fils conducteurs et dans les positions qui leur sont reliées au moyen de signaux d'entrée provenant d'au moins trois fils dans le dispositif de mesure d'électrocardiogramme; en l'absence d'erreur, exécuter un traitement consécutif sur les signaux reçus; en présence d'erreur, modifier le trajet de transmission des signaux d'entrée depuis les trois fils au moins, puis exécuter un traitement consécutif.
