A defibrillator does not restart the heart. It stops a dysfunctional rhythm (e.g. pulseless tachycardia: beating too fast without effective pumping, or fibrillation: irregular beating without pumping) in the hope that the heart's intrinsic mechanisms will restore an effective rhythm. If a first responder arrives on a scene and the person has been unconscious for more than a few minutes, they will do two minutes of CPR first to remove metabolic waste products and bring in fresh oxygen. Then they will shock. After a shock, they will immediately resume CPR - remember, the shock stops the heart, not starts it. If this is ineffective, the cycle continues until more advanced help arrives, along with more shocks delivered at several minute intervals. (Protocols vary by locality, and AEDs vary, get trained or follow the instructions on the AED.) Of note, a flat-lined ECG (asystole) is not shockable - you can't stop a rhythm that doesn't exist. However, you can have a total lack of heartbeat without flatlining. The heart is effectively on idle but not doing anything. In such a case, a defibrillator can still work well.

This is false bc in open hear surgery the heart has to be stopped first b4 it can be worked on. Then the surgeon uses little paddles to restart the heart. My wife has had 2 surgeries on her heart plus several small a- rhythm resets

False. Defibrillators just correct a heart that is beating out of sync.. If your heart stops, that's the end of it.

Why do you see them shocking the heart at the end of the bypass operation. The heart is not beating

I had open heart surgery twice. The first time my heart was stopped the second time it was not. Open heart surgery on a beating heart is a specialized skill that has certain benefits over traditional heart.surgery.

That is not correct, a defibrillator is used to cancel out all electrical impulses in the heart if the heart is not beating as it should (e.g. during cardiac arrest) so that the pacemaker may resume control. Unfortunately it can not be used to restart a heart, other wise it would be called a miracle

It RESET your heart it did not RESTART it. This is where most people and it seems every TV show and movie get it wrong. It effectively stops you’re heart so your body may reset it to factory stettings. This is why using a defibrillator on someone can kill them because it will stop the heart

correct if your heart has stopped you are DEAD a defriballator will not bring you back i'm afraid---don't take as gospel what you see in tv programs same as when you see them jump when shocked-doesn't happen
