Figure 2.

Examples of electroanatomic maps of a low voltage complex fractionated atrial electrogram (CFAE) ablation. (A) Antero-posterior view and (B) Postero-anterior view of the left atrium (LA) after ablation. The left side of Figure A/B is a CFAE map and the right side a voltage map. (C) During an LA roof area CFAE ablation, atrial fibrillation converted into atrial tachycardia (AT). (D) During a CS os ablation, the AT terminated, and sinus rhythm was restored in the patient. The CFAE area was tagged with an azure dot. The ablation points are the pink and red dots. The blue dot is the AT termination site.
