Someone would be called clinically dead when their heart stops beating.
I'm pretty sure that clinically dead is what they call people who's heart is not beating, meaning that someone could have a defibrillator used on them and then recover... not sure, but I think that's it.
The longest recorded time someone has been clinically dead and then revived is 4 hours. This occurred in the case of a young girl named Tiffany Bennett, who suffered from hypothermia after falling into an icy stream. She was successfully resuscitated after her heart had stopped beating for 4 hours.
Although clinically dead for two minutes, the patient was successfully revived. Brain injuries can result in a clinically vegetative state.
A person who over exaggerates is often called a drama queen. Clinically the tendency to over exaggerate is called histrionic.
No one can come back from the dead. In exceptional circumstances someone can revive who has been pronounced clinically dead. However this is extremely rare and is only possible over a very short time frame.

If someone is clinically dead, a defibrillator will actually do absolutely nothing. What is does do is shock an irregular heart beat back into sinus rhythm (a normal beat) that would otherwise lead to death.
brain
Once a person's heart stops beating, delivering oxygen and nutrients to their cells ceases, resulting in irreversible damage. The brain suffers particularly quickly, leading to permanent loss of function. Current medical technology is unable to reverse this extensive damage, making it impossible to revive someone who has died.
a person can be clinically dead when he or she has not shown brain waves for 24 hours and has no reflexes, respiration or heart beat. At such time most of the body is biologically alive and its organs may be used for transplant
