Because the heart works to pump blood throughout our body. No blood, no life. Your heart stops working, our brain, which allows us to do everything we do, would die along with the rest of our body which is entirely dependent on the brain. The brain being quite dependent on how the heart beats, having it beat properly.

The heart would continue to beat in this situation, although at a slower pace._____________________________________________________________________ It depends on how well the body can cope with a slow heart rate.
