(a) In this example of successful arrhythmia termination, four 10 ms shocks (10 V/cm) were applied during one CL of AF (55 ms). OAPs are shown from the RAA and LAA before and after termination by the shocks shown. Arrhythmia wavefronts, reconstructed from the dV/dtmax, before, during, and after shock application. (b) In this example of unsuccessful termination, three 10 ms shocks (2 V/cm) were applied during one CL (50 ms). Arrhythmia wavefronts before, during, and after shock application. Arrhythmia wavefront frames indicated by red lettering indicate those reconstructed during shock application.
