CA 2459197

The invention presents techniques for monitoring the magnitudes of representative filtered EGM signals over time. In a typical implementation, a group of digital peak values is generated in a time period and a representative digital peak value is selected for the time period. By comparing representative peak values for several time periods, changes in signal efficacy can be identified.

L'invention concerne des techniques permettant de surveiller les amplitudes de signaux d'EGM filtrés pendant une certaine durée. Dans une mise en oeuvre type, un groupe de valeurs de crête numériques est généré pendant une certaine durée et une valeur de crête numérique représentative est sélectionnée pour cette durée. La comparaison des valeurs de crête représentatives de plusieurs durées permet d'identifier des changements au niveau de l'efficacité des signaux.
