from the brain. The heart will continue to beat for a while even
though the brain is dead, as long as there is oxygen entering the
body and carbon dioxide is being removed through the lungs.
However, because the brain is dead and cannot regulate the
heartbeat, it may be irregular or erratic, and it will stop in almost
all cases within 24 to 48 hours, no matter how much the doctors
and nurses try to prevent it.
