A man died while waiting for an ambulance after crews were late because the call handler did not pass on his details.

An emergency call was made after a man suffered a cardiac arrest at a house in Aberdeen.

A computer blackout forced calls to be diverted to the Scottish Ambulance Service's control room in South Queensferry, Edinburgh, on May 19.

The handler noted the man's details while explaining to the caller how to carry out CPR until the ambulance arrived.

It emerged the note was not passed to the dispatch team and by the time the error was realised and an ambulance arrived 33 minutes later, it was too late to save the man.

Health secretary Shona Robison said: "I am deeply concerned to hear about this tragic incident and my thoughts are with the family and those affected.

"I have spoken directly to the chief executive of the ambulance service to ensure that a full and urgent review of this case is undertaken and made clear that its findings must be acted upon."

A Scottish Ambulance Service spokeswoman said: "We received a call at 2.46am on Friday May, 19, to attend an address in Aberdeen and arrived at 3.19am.

"CPR advice was provided by our call handler. The response time is longer than we would expect and the incident was reported by the ambulance control centre staff involved.

"We are currently undertaking a full investigation of the events. Initial findings indicate that the circumstances around this incident were extremely unusual."

She added: "We have contacted the patient's family to offer our sincere condolences and to hear their recollection of the response as part of our investigation.

"We will share our findings with the patient's family and address any recommendations."
