Fagilyu Mukhametzyanov, 49, woke in her coffin to the horror of mourners paying their last respects.
Following her revival, Mrs Mukhametzyanov started screaming and was rushed back to hospital where she was again confirmed deceased.
Her husband Fagili explained to the Austrian Times: "Her eyes were moving and we immediately rushed her back to the hospital.
"But she only lived for another 12 minutes in intensive care before she died again, this time for good. I am very angry and want answers. She wasn't dead when they said she was and they could have saved her."
Meanwhile, a hospital spokesman announced that the malpractice will be reviewed, declaring: "We are carrying out an investigation."
