HUSBAND John Fraser, who collapsed and died as he made sandwiches with his wife, could have suffered from a mysterious Sudden Adult Death Syndrome, an inquest heard.

Mr Fraser, 33, of Foxglove Way, Calne, died on April 13 the inquest heard on Wednesday, July 5.

He was standing in the kitchen with his wife Sheila at 9.45pm, making lunch to take to work the next day, when he collapsed and hit his head on a kitchen unit.

Mrs Fraser called an ambulance and unsuccessfully tried to resuscitate him.

Mr Fraser had felt dizzy earlier in the evening when he was sitting down, but pathologist Dr Jeanette Armstrong said she could not discover a positive cause of death.

She could not find evidence of a heart attack and suggested he may have died of Sudden Adult Death Syndrome, which was related to the Sudden Infant Death Syndrome.

Wiltshire coroner David Masters said it was probably a heart problem, such as an electrical disturbance in the heart's rhythm, identified as the Sudden Adult Death Syndrome. He said no condition could be identified with certainty, but recorded the cause of death was natural.
