Figure 3. Acute Termination of AF (two sources) to Sinus Rhythm By FIRM Ablation.

Figure 3

(A) Right atrial rotor (clockwise) and simultaneous left atrial focal impulse (arrowed) during persistent AF in a 47 year old man. (B) FIRM ablation at right atrial rotor terminated AF to sinus rhythm in 5.5 minutes (see Supplemental movies 4–5). Note the slowing of AF rate during ablation. The left atrial focal impulse source was also treated by FIRM ablation. The patient is AF-free on implanted cardiac monitor at > 1 year. Scale bars 1 cm, 1 second; CS: coronary sinus electrogram. Atrial orientations as in figure 1.
