== Lazarus Syndrome ==

'''Lazarus Syndrome''' (''pronunciation:'' la-zuh-rus sin-drome), also known as '''autoresuscitation after failed cardiopulmonary resuscitation''', is a rare and unexplained medical phenomenon that involves the spontaneous return of [[circulation]] (''pronunciation:'' sur-kyuh-lay-shun) after failed attempts at [[resuscitation]] (''pronunciation:'' ree-suh-si-tay-shun).

== Etymology ==

The term "Lazarus Syndrome" is derived from the biblical character [[Lazarus]] (''pronunciation:'' la-zuh-rus), who was resurrected by Jesus four days after his death. The syndrome was named so due to the unexpected and seemingly miraculous return of life signs after the patient has been declared clinically dead.

== Overview ==

Lazarus Syndrome is an extremely rare event, with only a handful of documented cases worldwide. It is often associated with the administration of [[cardiopulmonary resuscitation]] (CPR), particularly the use of [[adrenaline]] (''pronunciation:'' a-dre-na-lin) in the resuscitation process. The exact cause of Lazarus Syndrome is unknown, but it is believed to be due to a buildup of pressure in the chest cavity, which can cause the heart to start pumping again once the pressure is released.
