Figure 2. Pacing maneuvers indicative of MI block and PMF. A:
Pacing from LAA with MI conduction before MI ablation in the
1st procedure. B. Pacing from LAA with complete
reversal in CS sequence after MI ablation in the 1stprocedure. C: Pacing superiorly of the MI line at the beginning of the
2nd procedure before any ablation. D: Clockwise PMF
with CL=250ms. E: Termination of the arrhythmia by ablating the gap in
MI (Video 3). F: Reconfirmation of MI block.
