A woman has died of heart failure caused by the shock of waking up at her own funeral.

Fagilyu Mukhametzyanov came to as grieving relatives prayed around her open coffin.

The horrified 49-year-old began screaming when she realized they were getting ready to bury her.

She was rushed back to the hospital, where doctors had declared her dead from a suspected heart attack.

"Her eyes fluttered and we immediately rushed her back to the hospital," her husband Fagili, 51, said. "But she only lived another 12 minutes before she died again, this time for good."

Now Fagili plans to sue the hospital.

"I am very angry and want some answers. She wasn't dead when they said she was and they could have saved her," he said.

A spokesman at the hospital in Kazan, Russia said they are carrying out an investigation.
