When should sudden cardiac arrest be assumed in an athlete?

Sudden cardiac arrest should always be assumed in a collapsed and unresponsive athlete because this condition can occur unexpectedly and without prior warning signs. In the context of athletics, a player's sudden collapse can indicate a serious medical emergency, and immediate action is critical.

The rationale behind this assumption is based on the fact that quick response times significantly influence the chances of survival. Recognizing the possibility of cardiac arrest ensures that appropriate measures, such as calling for emergency medical services and initiating CPR or using an Automated External Defibrillator (AED), are taken promptly.

Assuming cardiac arrest in such situations also helps in differentiating between various causes of a collapse. While visible injuries or a history of heart conditions might seem relevant, they do not guarantee that other issues, such as a sudden cardiac event, are not occurring. Timely recognition and response are key, making this approach the most effective for ensuring the safety and care of the athlete involved.
