An investigation has been launched into the death of a mother of two who fell unconscious while waiting in an accident and emergency (A&E) unit.
The woman was found in a chair underneath her coat on 19 January at Queen's Medical Centre in Nottingham.
It is understood the 39-year-old, who was triaged on arrival complaining of a headache, waited for more than seven hours to be seen by a doctor.
She died of a brain haemorrhage two days later.
The BBC understands the woman was observed by nurses but had not been seen by a doctor.
It is also understood that she was found by staff when her name was eventually called out to see a doctor and she did not respond. She died while in intensive care.
Dr Keith Girling, the medical director at Nottingham University Hospitals NHS Trust, which runs the hospital, said: "I offer my sincere condolences to the family at this difficult time. "An investigation, which will involve the family, will now take place and until this has been concluded, we are unable to comment further."
Depending on the outcome of the review, the case could be escalated to an external independent investigation. The coroner has been informed.
Speaking to the BBC, Nottingham South MP Lillian Greenwood offered her condolences to the family, adding she was "deeply shocked". "It is now really important that there is a full investigation into this and to get to the circumstances into this case," she said.
