Implantable Cardioverter Defibrillator Electrogram Adjudication for Device Registries: Methodology and Observations from ALTITUDE

Abstract

This method of adjudication of a large volume of stored EGM data prior to device therapies will allow new observations in regards to device performance and has the potential to improve device programming and design. There was substantial interreviewer agreement for rhythm classification. Agreement was greater for dual-chamber compared to single-chamber devices, indicating the atrial lead adds diagnostic value in rhythm interpretation.
