Fig 3. Simulations on the atrial mesh of Patient 2 of (a) an initiator-type FS with a CL of 180 ms at an LA focal site (αLA = 0.2, βLA = 0.2, red star), and (b) a driver-type FS with a CL of 210 ms at the same site (red star), with full videos (S1 and S2 Videos).
The white spheres in (a) show phase singularity points, and the red arrows show the wavefront movement of rotors. The time since the first firing of the FS was indicated above each frame. A sustained rotor of total duration 547 ms was presented in (a), but no rotor was detected in (b).
