Abstract
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.
