The fact that you would ask such a question suggests that you don't know much about devices like automated external defibrillators.
The so-called automated external defibrillator, or AED, is an intelligent medical device that reads and analyzes the heart rhythm and defibrillates patients identified with a defibrillable rhythm. Because of its safety and simplicity, it can be used by the general public, even non-medical personnel.
As for your AF, first of all, the built-in program of the AED does not recognize the readout; in addition, I don't know if you've ever had an ECT in the past, but it's very scary to be shocked by a defibrillator's strong electrical current while awake, and ECT for AF is routinely administered under anesthesia, so it's not practical to use an AED for AF in this regard.
