Abstract:
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.

Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
