Background Effects of nonparoxysmal atrial fibrillation (non‐ PAF ) ablation targeting complex fractionated atrial electrogram ( CFAE ) areas and/or low voltage areas ( LVA s) are still controversial. Methods and Results A recently developed online real‐time phase mapping system (Ex TR a Mapping) was used to conduct LVA mapping and simultaneous Ex TR a and CFAE mapping in 28 non‐ PAF patients after pulmonary vein isolation ( PVI ). Nonpassively activated areas, in the form of meandering rotors and/or multiple wavelets assumed to contain non‐ PAF drivers, partly overlapped with CFAE / LVA s but not always coincided with them. Conclusion Real‐time rotor imaging, rather than conventional indirect indicators only, might be very useful for detecting non‐ PAF drivers.
