Characterization of Complex Fractionated Atrial Electrograms by Sample Entropy: An International Multi-Center Study
Atrial fibrillation (AF) is the most commonly clinically-encountered arrhythmia.Catheter ablation of AF is mainly based on trigger elimination and modification of the AF substrate.Substrate mapping ablation of complex fractionated atrial electrograms (CFAEs) has emerged to be a promising technique.To improve substrate mapping based on CFAE analysis
