London, August 9 : Four members of the same family in England have been diagnosed with a rare heart condition called Long QT, which can claim their lives any moment.
Rob Griffiths, 44, and three of his four children—Rhys, 20, Rhiann, five, and Nelly, two—suffer from a genetic defect that can cause "sudden death syndrome".
Long QT, which is thought to affect just one in 5,000 people, is one condition in which otherwise fit and healthy people may suffer fatal heart failure.
According to reports, Rhys was the first member of the family to be diagnosed, at the age of 15, after he collapsed while on holiday.
