Abstract

Implantable defibrillators have evolved from simple event counters to sophisticated diagnostic monitoring units capable of storing electrocardiographic information surrounding arrhythmia events and device therapy. In this review, the nature and characteristics of these stored electrocardiographic recordings are discussed and examples displayed. Potential benefits and limitation of stored electrogram analysis are described with respect to both clinical utility and the ability to enhance our understanding of ventricular arrhythmogenesis. Finally, future developments to improve data storage, retrieval, and analysis are identified.
