A retrospective study from Sweden found that sudden arrhythmic death syndrome (SADS) accounts for 22% of sudden cardiac deaths in young people, with identifiable warning signs including syncope, psychiatric diagnoses, and abnormalities in electrocardiogram findings. Investigators noted the potential for intervention during medical encounters to identify individuals at risk and reduce the occurrence of SADS.
