Sudden cardiac arrest (SCA) is an uncommon but devastating event among young adults. While inherited cardiomyopathies and channelopathies represent an important proportion of sudden deaths, coronary artery disease remains a significant contributor in this age group. ECG findings are essential to guide the first steps of diagnostic work-up of SCA, but sometimes can overlap between different etiologies. In this article we present a 16-year-old female who experienced SCA during vigorous swimming whose ECG was compatible with long QT syndrome. However, evaluation of the coronary anatomy provided the diagnosis of Kawasaki disease.
