Disrupting the heart's rhythm is way easier than restoring it. Especially if the disrupting current got in through punctured skin (which the defibrillator is not allowed to do)

This is very bad advice. A couple amps at 220VAC is devastating if actually delivered inside your body. The reason people routinely survive mains shocks is the current doesn't actually get through due to intact dry skin, pure (poorly conducting) water, no path across their body, or no path to ground, which is all a matter of luck.

But that's what a defib does. It disrupts your heart's rhythm. And then you hope it goes back to normal.
