title: Extraction of physiological and clinical information from intra-atrial electrograms during atrial fibrillation: review of methods.
abstract: This paper presents a review of the evolution of methods and algorithms for the analysis of intra-atrial recordings, with special emphasis to the extraction of physiological and clinical information during atrial fibrillation. The principal time-domain and frequency-domain methods of electrogram analyses are described, and their physiological interpretation and clinical applications are discussed. In addition, the recent findings from complex system theory and chaos theory approaches are highlighted.
