Panoramic Electrophysiological Mapping But Not Electrogram Morphology Identifies Stable Sources for Human Atrial Fibrillation: Stable AF Rotors and Focal Sources Relate Poorly to Fractionated Electrograms

Background-The foundation for successful arrhythmia ablation is the mapping of electrical propagation to identify underlying mechanisms. In atrial fibrillation (AF), however, mapping is difficult so that ablation has often targeted electrogram features, with mixed results. We hypothesized that wide-field of view (panoramic) mapping of both atria would identify causal mechanisms for AF and allow interpretation of local electrogram features including complex fractionated atrial electrograms (CFAE).
