My mums heart stopped after they cut away a plaster cast in Bulgaria!
Shes ok, and was after the doctor & my father bought her back after about 3 mins.
She had broken her leg, the bulgarian hospital had done a great job. After 8 weeks or so she had it removed, the doctor said there shall be some pain as the blood flows back. After a minute, she collapsed & went unconsious before her pulse stopped & she lay there dead for over a minute!!
My father was obviously scared shitless & the doctors bought her back! Fuck me I thought when she told me the next day!
Alls well and ends well I suppose!
