Figure 2: Yield of Genetic Cardiovascular Conditions from Familial Evaluation Following Sudden Arrhythmic Death Syndrome.

Right: Pie chart showing the causes of sudden cardiac death in 89 sports deaths in young athletes referred to a tertiary cardiac centre in the UK over a duration of 12 years. Left: Bar chart showing the yield of genetic cardiovascular conditions from familial evaluation series following sudden unexplained death and/or SADS. ARVC = arrhythmogenic right ventricular cardiomyopathy; BrS = Brugada syndrome; CPVT = catecholaminergic polymorphic ventricular tachycardia; DCM = dilated cardiomyopathy; HCM = hypertrophic cardiomyopathy; LQTS = long QT syndrome; LVH = left ventricular hypertrophy; MI = myocardial infarction; SADS = sudden arrhythmic death syndrome. Data taken from de Noronha et al.,[15] Behr et al.[17] and Van der Werf et al.[45]
