I am sorry for your loss.
1. Don't learn CPR or emergency care from TV- they are more interested in drama than accuracy. People who know the stuff often cringe at most medical shows inaccuracies. (Yes, even House!)
2. Flat-lined hearts (asystole
) cannot be shocked back to a rhythm. The thing about the shocks (defibrillation
) is that it stops a bad rhythm and allows the heart to restart a good one. It does not actually restart the heart.
3. A 'bad heart' is hard to restart and get going on its own. Sadly, CPR and other heroic measures are not often successful in the real world.
