Vigorous physical activity increases the risk of sudden cardiac death (SCD) and acute myocardial infarction (AMI) but there is no standard definition as to what constitutes an exertion-related cardiac event, specifically the time interval between physical exertion and cardiac event. A systematic review of studies related to exertion-related cardiac events was performed and the time interval between exertion and the event or the symptoms leading to the event was looked for in all the articles selected for inclusion. A total of 12 of 26 articles "suggested" or "defined" exertion-related events as those events whose symptoms started during or within 1 h of exertion. Others used definitions of 0.5 h, 2 h, "during exertion", "during or immediately post exertion" and "during or within several hours after exertion". It is suggested, therefore, that the definition of an exertion-related cardiac event be established as a cardiac event in which symptoms started during or within 1 h of physical exertion.
剧烈的身体活动会增加发生心源性猝死（SCD）和急性心肌梗死（AMI）的风险，但目前尚无关于什么是与体力活动相关的心脏事件的标准定义，特别是体力活动与心脏事件之间的时间间隔。对与体力活动相关的心脏事件的研究进行了系统评价，并在纳入的所有文章中寻找体力活动与事件或导致事件的症状之间的时间间隔。在 26 篇文章中，有 12 篇“建议”或“定义”了与体力活动相关的事件，即症状在体力活动期间或体力活动后 1 小时内开始的事件。其他文章使用了 0.5 小时、2 小时、“在体力活动期间”、“在体力活动期间或之后立即”和“在体力活动后数小时内”的定义。因此，建议将与体力活动相关的心脏事件定义为症状在体力活动期间或体力活动后 1 小时内开始的心脏事件。
