Leslie Dunn has entered the list of the oldest people in the UK to get a pacemaker. This 106-year-old great-grandfather of two was preparing tea for his friends, and meanwhile he got unconscious and fell on the floor.

He was immediately taken to the Colchester General Hospital, and after observing his heart beat for a week, doctors declared he needs to get a pacemaker fitted.

Dr. Allan Harkness, the cardiologist who performed the Dunn’s surgery, announced that he is aware of a few patients who have got pacemaker at such advanced age, and with the advancement in technology, age is no longer considered to be a barrier for the treatment. He even told a patient has got pacemaker fitted at the age of 107 in Scotland, and in their hospital, they are performing such surgeries since 2006, with the last oldest patient aged at 101 years.

Dunn who has retired from the post of a major from Coldstream Guards in 1956, underwent four hours surgery, and currently is in the effect of local anesthesia, and would return home by next week.

Dr. Harkness revealed that according to the Department for Work and Pensions report, by 2066 there will be half a million people aged 100 or more in Britain.
