Comment: November 30th 2006 This boy had a brief syncopal spell 2 weeks before this event but was generally considered very healthy. At the time of his collapse he was playing in the snow with his brother and was resusitated with a thump on the chest once it was realised that he was unconscious. There was no family history of LQTS. He received an AICD and the rest of his family is being screened.
