I am a paramedic and an AHA CPR instructor.

We are making orthogonal points...

If someone is being defibrillated, then they have no pulse. The person using the AED may not know that, but the AED does.

You initially said:

> Since they were performing CPR on her, it's likely she had a very weak or no heartbeat (asystole), which defibrillators are no good with.

You seem to be saying that if a person doesn't have a pulse, they must be in asystole, and don't need a defibrillator, which is dangerously untrue. The only reason you do CPR is to preserve the heart and brain long enough to use a defibrillator. In fact, the only circumstances under which someone should be defibrillated are certain types of pulseless cardiac activity.
