Answer:
death occurs if it stops for too long
Explanation:
Cardiac arrest is the sudden loss of cardiac function, when the heart abruptly stops beating. Unless resuscitative efforts are begun immediately, cardiac arrest leads to death within a few minutes. This is often referred to by doctors as "sudden death" or "sudden cardiac death (SCD)."
According to Dr. Sam Parnia, death is defined as the time when the heart has stopped beating. The blood from the heart then fails to reach the brain to sustain it. This means all the reflexes of the base of the brain including “gag reflex” or “pupil reflex in the eyes” are all lost almost instantaneously.
