Robert Todman, of Portland Close, Hailsham, called out to his wife Sheila and she rang an ambulance. The 75-year-old was taken to the DGH but died the next day.
An inquest heard that the retired development engineer also suffered from Paget's Disease of the skull, which affects bone growth. Bone breaks down more quickly and when it grows again it is softer than normal bone.
On the day of the incident on December 7 last year Mr Todman had been ironing.
Mrs Todman said, "I heard him call 'Oh no, it's happening again'. I saw him falling to the floor but he didn't hit his head. He started to be sick and said he had a bad headache.
"He started to produce blood in his vomit and I rang an ambulance. I saw there was blood in his ear."
She told the hearing that her husband of 41 years had had around five vertigo attacks in the past three-and-a-half years. She said he had had a similar attack on December 5 last year. On that occasion Mr Todman had said the attack was different as the room was stationery and he felt that he was spinning around, rather than the opposite. She thought the attack two days later was a similar one.
A post mortem examination gave the cause of death as a left sub hematoma due to the fall and that Paget's Disease had been a contributory factor in his death.
Coroner Alan Craze told the hearing Mr Todman had suffered his head injury during the fall. He recorded a verdict of accidental death.
