A, Comparison of complex fractionated atrial electrograms (CFAE) grade and electrogram voltage between atrial fibrillation (AF) sources and surrounding ipsilateral atrium for paroxysmal and persistent AF patients (B) preserved electrogram amplitude (≈0.4–0.5 mV) without CFAE at right atrial rotor in persistent AF, where focal impulse and rotor modulation (FIRM) hyperacutely terminated AF to sinus rhythm in 48 seconds before any other ablation. The patient remains AF-free after 15 months on implantable ECG monitor. Right atrial orientation as in Figure 2A.
