So if a heart stops you can massage, pump or shock it back to life, and surgeons even stop a heart on purpose before firing it back up, so why can’t they do that 100 percent of the time? What is it that makes a heart stop and never come back? If the brain is working then surely the heart should always come back?
In: Biology
If your hearts stops beating there is normally a reason for it (e.g. something is damaged). And depending on what the reason is, you will not be able to “restart” it (or at least not for long).
As an analogy: If you have a car, where the battery is empty, you can jump start it using another car. But that will not work, if the motor of your car is broken. Trying to jump start your car then might be able to rotate the motor for a quick motor, but you will not be able to drive with it.
