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.
