Organization of Frequency Spectra of Atrial Fibrillation: Relevance to Radiofrequency Catheter Ablation

Introduction: We hypothesized that the frequency spectra of fibrillatory electrograms may reflect the complexity of activities perpetuating atrial fibrillation (AF). To test this hypothesis, we evaluated the frequency spectra in patients with paroxysmal AF in relation to catheter ablation.
