Abstract:
Sudden cardiac death in a young athlete is a tragic and marking event, even though the media attention it gets is more important than its incidence (1-2/100000 per year). The main etiology is hypertrophic cardiomyopathy, followed by coronary artery anomalies. Sometimes signs of myocarditis are found at autopsy. The pre-participation examination recommandations ask for oriented history and physical examination, routine EKG being controversial. A systematic screening program in Italy has reduced the occurrence of such deaths, which statistics are non-existant in Switzerland. It would be appropriate to implement a standardized pre-participation examination, as well as to make sure that the trainers, teachers and athletes themselves are able to recognize the frequent warning symptoms.

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...
