If it’s possible to restart a heart, why can’t they do it every single time?

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?

Technically, we can. The heart isn’t necessarily the issue. We just need the heart so it can get oxygen to the head and get the brain back online. If the brain won’t come back, then it can’t pick up the slack and take back reigns of keeping the heart pumping. The heart can’t force the brain to cooperate.
