心血管对实验室应激的反应性可以预测日常生活中的心血管负荷。然而，先前的研究对这一假设提出了质疑。本研究探讨了心率（HR）之间的关联，以公开演讲任务和动态HR在一天。心电图，身体运动，和心理社会变量（影响，上下文）记录在111人。动态心率与积极和消极情绪呈正相关。实验室基线HR可显著预测动态HR，但HR反应性不能。在实验室中，瞬时负面情绪和心脏反应性的相互作用也不显著。然而，一个显着的基线HR和反应性的相互作用表明，当基线是高的，有一个积极的关系，HR反应性和动态HR.Findings结果表明，基线时，必须考虑旨在预测心血管负荷在日常生活中。
Cardiovascular reactivity to laboratory stress might predict cardiovascular load in everyday life. However, previous research throws doubt on this hypothesis. This study examined associations between heart rate (HR) to a public speaking task and ambulatory HR throughout a day. Electrocardiogram, bodily movement, and psychosocial variables (affect, context) were recorded in 111 individuals. Ambulatory HR was positively associated with both positive and negative affect. Baseline HR in the laboratory significantly predicted ambulatory HR, but HR reactivity did not. The interaction of momentary negative affect and cardiac reactivity in the laboratory was also not significant. However, a significant interaction of baseline HR and reactivity indicated that, when baseline was high, there was a positive relation between HR reactivity and ambulatory HR. Findings suggest that baseline has to be considered when aiming to predict cardiovascular load in everyday life.
