I was told in introduction to electronica that sadly it's terribly easy, and the teacher claims he has seen it happen. If you manage to take a 9 volt battery and scratch yourself with it (very easy with the negative contact, not so easy with the positive one), and both sides contact blood directly, the current may flow through your hart and may stop it (CPR will restart it, but that of course assumes someone's there to do it, and that people realize what's happened in the first place). I can't believe someone actually stuck essentially needles connected to a power source into his blood. What. The. Fuck.
