Figure 2.

Termination site of atrial fibrillation during the LVZ ablation (the red tag indicated by the arrow) (panel A) and an ECG and electrocardiograms at the time of the AF termination (panel B). AF was terminated and converted to SR during the LVZ ablation. The LVZ ablation was continued until the anteroseptal LVZ was completely ablated. The green tags indicate the LVZ ablation region. The bipolar electrograms recorded in the LA appendage, by the ablation catheter, and in the coronary sinus are shown (panel B). ABL, ablation catheter; AF, atrial fibrillation; CS, coronary sinus; LVZ, low‐voltage zone; LA, left atrium; LAA, left atrial appendage; SR, sinus rhythm
