An inquest in Northern Ireland has been told that an elderly man suffered a heart attack and died after a doctor at a Belfast hospital gave him the wrong dose of drugs.
The inquest heard that Walter Johnston, 92, from Newtownabbey, was being treated in the City Hospital in Belfast for a blood clot in his knee.
During the treatment, a junior doctor injected Mr Johnston with 100 times the correct dose of insulin.
After the injection, Mr Johnston's kidneys failed and he died a short time later.
In a letter to the inquest, the medic involved, Dr Muzamin Ahmad said he had not received any instruction in the handling of insulin, and thought that one unit of the drug was equivalent to 1ml.
Deputy State Pathologist Dr Alistair Bently said that although the patient who died was elderly and had a number of life threatening conditions, he did not believe he would have died at that time had he not received an insulin overdose.
