为了研究剧烈运动时原发性心脏骤停的风险，对133名既往无心脏病史的原发性心脏骤停患者进行了访谈。根据心脏骤停时的活动和习惯性剧烈活动的量对病例进行分类。通过与妻子或健康男性随机抽样的访谈，估计了社区成员在剧烈活动中花费的时间。在习惯性活动水平低的男性中，运动期间心脏骤停的相对风险与其他时间相比为56（95%置信区间，23-131）。在最高水平的习惯性活动中，男性在运动期间的风险也有所增加，但只有5倍（95%置信限，2-14）。在习惯性精力旺盛的男性中，心脏骤停的总体风险，即，在剧烈活动期间和不剧烈活动期间，只有久坐男性的40%（95%置信区间，0.23-0.67）。虽然在剧烈运动期间原发性心脏骤停的风险暂时增加，但习惯性剧烈运动与原发性心脏骤停的总体风险降低相关。
To examine to risk of primary cardiac arrest during vigorous exercise, the vives of 133 men without known prior heart disease who had primary cardiac arrest were interviewed. Cases were classified according to their activity at the time of cardiac arrest and the amount of their habitual vigorous activity. From interviews with wives or a random sample of healthy men, the amount of time members of the community spent in vigorous activity was estimated. Among men with low levels of habitual activity, the relative risk of cardiac arrest during exercise compared with that at other times was 56 (95% confidence limits, 23-131). The risk during exercise among men at the highest level of habitual activity was also elevated, but only by a factor of 5 (95% confidence limits, 2-14). Among the habitually vigorous men, the overall risk of cardiac arrest i.e., during and not during vigorous activity was only 40% that of the sedentary men (95% confidence limits, 0.23-0.67). Although the risk of primary cardiac arrest is transiently increased during vigorous exercise, habitual vigorous exercise is associated with an overall decreased risk of primary cardiac arrest.
