I was going to have part of the plot I was working where someone suddenly dies in a hospital bed. Not from something like Cancer where they know the end is near and it's just a matter of waiting, and not from something where it's a hospital mistake and they die in surgery. It has to be something where they appear fine one moment... they are just chilling in a regular hospital bed (maybe with a heart monitor or some kind of IV attached) and then suddenly they have a heart attack or stroke or something. Does anyone know of a realistic scenario where that could happen? I don't think it could be a heart attack or stroke on it's own because I would think that a hospital would be able to do something to keep you from dying to that. It would have to be something they didn't know about that just suddenly hit them. I'm thinking maybe they go to the hospital originally because of pain in their chest and they get checked out and nothing appears to be wrong at first, but then suddenly BAM they are gone. Maybe like a bad reaction to medicine or something.
