when does a body go into rigor mortis
Rigor mortis Rigor mortis (Latin: rigor "stiffness", mortis "of death"), the third stage of death, is one of the recognizable signs of death, caused by chemical changes in the muscles post mortem, which cause the limbs of the corpse to stiffen.[1] In humans, rigor mortis can occur as soon as 4 hours post mortem.[1]
Lazarus syndrome Lazarus syndrome, (the Lazarus heart) also known as autoresuscitation after failed cardiopulmonary resuscitation,[1] is the spontaneous return of circulation after failed attempts at resuscitation.[2] Its occurrence has been noted in medical literature at least 38 times since 1982.[3][4] It takes its name from Lazarus who, as described in the New Testament of The Bible, was raised from the dead by Jesus.[5]
