Unsuccessful defibrillation using five pulses, applied 60 ms apart.

The panel at t = 0ms shows the system before a defibrillating stimulus is applied. The next five panels show the system approximately 30ms after successive pulses are applied. Notice that soon after the last pulse is applied at t = 339ms, the ID is around 0.65, indicating that there will likely be pathways for spiral waves to reenter, as shown in the final two panels.
