Abstract
L'invention concerne un procédé de codage (200) destiné à coder et comprimer de façon efficace des données d'électrocardiogramme (ECG) optimisées, à utiliser dans un moniteur d'électrocardiographie ambulatoire. Des données d'ECG sont d'abord codées et comprimées (202) dans un procédé avec perte (202) puis ultérieurement codées et comprimées (203) dans un procédé sans perte. On obtient ainsi un rapport de compression significativement plus élevé que celui obtenu avec d'autres moniteurs de type Holter. Les exigences en matière d'espace de stockage et de consommation de pile sont réduites, ce qui contribue à une disponibilité à long terme du moniteur.
