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
Simple answer: Hearts stop for different reasons. The methods you mention work for some of those reasons and not all. Often it depends how damaged the heart is, but sometimes just the way it’s damaged.
By analogy, if people keep their cars from stopping by putting gas in them – I see people put gas in their cars to make them run every day – then why do some cars stop even with gas in them? Why doesn’t putting gas in all broken cars make them able to go again?
