Sport careers peak at different ages depending o...

The majority of sudden deaths in young athletes occur in the context of underlying inherited or genetic cardiac disorders. The evaluation of every athlete regarding underlying cardiac disease is impractical and therefore needs to be targeted at those who are at a higher risk. A practical approach would be to channel efforts towards athletes with cardiac symptoms, those with a family history of ...

PURPOSE OF REVIEW Participation in sports is on the rise, with young athletes training year round and specializing at earlier ages, predisposing them to sports-related injuries.
