New Robust Method of Atrial Electrograms Classification to Identify Complex Fractionated Atrial Electrograms

Popis výsledku v původním jazyce

Purpose: Complex fractionated atrial electrograms (CFAEs) may represent the electrophysiologic substrate for atrial fibrillation (AF). Progress in signal processing algorithms and pattern recognition systems to identify CFAEs sites is crucial for the development of AF ablation strategies. Methods: Head-to-head comparison of two methods for quantification of atrial electrograms (A-EGMs) with different degree of fractionation was performed using representative set of 1.5s A-EGMs (n = 113) that were blindly ranked by 3 independent experts into 4 categories: 1 - organized atrial activity; 2 - mild; 3 - intermediate; 4 - high degree of fractionation. First method (M1) assessed the average interval between discrete A-EGM spikes using algorithm previously implemented in commercially available electroanatomic mapping system.
