The arrhythmia accelerated back to the VF zone, the
seventh shock is delivered. The arrhythmia persists in
the VF zone so the eighth (and final) shock is delivered.
A sixth shock is delivered
since the arrhythmia is in
the VF zone.
The arrhythmia decelerated to a lower zone, an
additional shock would not be delivered until the
arrhythmia accelerated back to the VF zone.
