Grim toll of sudden heart death

"On Friday 5 October last year, Tom Clabburn did not wake up for school. Tom was just 14 when he died suddenly and completely unexpectedly from an undiagnosed heart condition. He was a bright, funny, active, and seemingly healthy teenager - the kind of boy everyone liked. In the UK, 12 young people die from an undiagnosed heart condition every week. They are people who inherited a structural abnormality or an electrical fault of the heart. This new figure has been collated by the charity CRY - Cardiac Risk in the Young - and denotes deaths among people up to the age of 35. It is based on data from the Office of National Statistics for 2005, and represents an increase of 50% on the previous estimate of eight deaths a week" - BBC
