Figure 2. Detailed mapping and ablation approach. AF = atrial fibrillation; AT = atrial tachycardia.
* Unstable AT is defined as having continuous circuit modification.
† Spatiotemporal dispersion mapping was biatrial in all patients but 1, in which after failed rotor ablation in the LA, sites with spatiotemporal dispersion were successfully targeted in the LA before considering RA rotor mapping.
