The entity of sudden cardiac death in young athletes has been known since the year 490 B.C. when young Greek soldier Phidipides had run the distance from Marathon to Athens and suddenly fell down dead. In the last twenty years, sudden death of famous athletes have attracted huge attention of medical and social community; afterwards both American and European Cardiology Societies started to publish periodically guidelines for preparticipation screening. These guidelines have focused on both identifying athletes with potential cardiovascular risk for sudden death and eligibility conditions for athletes participating in competitive sports. Structural and functional abnormalities causing sudden cardiac death in young athletes have been identified by autopsy-based studies. Unrecognized congenital cardiovascular abnormalities associated with excessive physical effort create background for electrophysiological instability and occurrence of malignant ventricular tachyarrhythmia and consequent death. The most frequent causes of sudden cardiac death in young athletes include hypertrophic cardiomyopathy, anomalies of the coronary arteries and idiopathic left ventricular hypertrophy. Current ACC/AHA & ESC guidelines should be widely used in order to reduce potential sudden cardiac death in young athletes.
To our knowledge, this is the first reported case of pacemaker implantation, with passive electrode, through a persistent left superior vena cava via the right subclavian vein. This case demonstrates that such an approach, when necessary, can be used successfully.
Introduction of electrocardiogram recording into the screening protocol in athletes increases the sensitivity of evaluation and may help to discover asymptomatic cardiovascular diseases that may cause sudden cardiac death. Special attention and further assessment are required when the above potentially pathological electrocardiogram changes are found in athletes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
