[Stored electrograms in pacemakers and ICD systems from the Sorin Group].

Stored electrograms (EGMs) can improve therapy with pacemakers and ICDs by detecting technical problems (e.g., over- or undersensing) and medical problems (e.g., atrial tachyarrhythmias). Analysis of stored EGMs and their interpretation requires knowledge about EGM recording (e. g., channels, summation EGM) and marker annotations. This review presents stored EGMs in pacemaker and ICD systems from the Sorin Group with tips on the potential and interpretation of memory capabilities.
