In a rare example of a phenomenon known as Lazarus Syndrome, a 23-year-old man came back to life 30 minutes after doctors pronounced him dead. Doctors at the Royal Preston Hospital declared Michael Wilkinson dead on February 1.
However, half an hour later, doctors realised that his pulse had returned, reports the Telegraph.
Wilkinson survived for two days before being pronounced dead a second time.
An inquest heard that his return to life was known as Lazarus syndrome - the spontaneous return of circulation after attempts to resuscitate fail.
There have only ever been 38 cases recorded worldwide.
The syndrome takes its name from the biblical story of Lazarus, who was raised from the dead by Jesus.
John Whittaker, a consultant at the Royal Preston's accident and emergency department, said it was "not a small thing" to pronounce a patient dead. "You make absolutely certain," he added.
Wilkinson had collapsed after an evening in which he had enjoyed a number of drinks with his family.
However, tests showed that alcohol played no part in the incident.
A post mortem conducted at the Royal Blackburn Hospital found that he had an undiagnosed heart condition in which his left ventricle had become abnormally thickened.
