Cardiac history is important to obtain, especially that of dysrhythmias and syncope. Ion channelopathies and sudden arrhythmic death syndromes, including Brugada syndrome and prolonged QT syndrome, should be considered [27] ; however, this cause of drowning is probably uncommon. Lunetta et al looked for genetic mutations in 63 drowning victims and failed to document one case of long QT founder gene mutation. [49]
