Abstract
La présente invention concerne un système et un procédé de reconstruction d'informations d'activation cardiaque donnés à titre d'exemple. Un signal d'analyse et un signal de référence sont traités pour déterminer s'il existe un premier point de changement dans une première dérivée d'ordre sélectionné du signal d'analyse par rapport à une première dérivée d'ordre sélectionné du signal de référence au-dessus d'un premier seuil. Le signal d'analyse et le signal de référence sont traités pour déterminer s'il y a un second point de changement dans une seconde dérivée d'ordre sélectionné du signal d'analyse cardiaque au-dessus d'un second seuil. Un temps de début d'activation est attribué dans le signal cardiaque d'analyse au niveau d'un point sur la base d'une association mathématique du premier point de changement et du second point de changement pour définir une activation cardiaque indiquant un battement dans le signal cardiaque d'analyse.
