Most GPs will encounter at least one case of sudden arrhythmic death syndrome (SADS) during their career. They may have to evaluate a young person at risk of SADS or offer support and screening to family members. GPs are usually the first point of call for families who have experienced the loss of a young relative. In England alone, SADS is responsible for 544 deaths per year. A significant proportion of cases may be preventable. First-degree relatives should be referred to an expert cardiac centre for comprehensive evaluation to identify individuals at risk.
