本文研究了心血管对实验室应激反应的时间稳定性。先前接受冷加压和电击回避反应时间任务的受试者被带回使用几乎相同的任务进行重新测试。两个疗程共有的心血管变量包括心率、收缩压和舒张压以及射血前期。相关性进行了计算，以检查在休息和两个任务期间的四个心血管变量在两个会议的反应的关联。心率和收缩压的相关性在所有任务和休息时都很高，而舒张压和射血前期的相关性不一致。舒张压升高推测是由于β-肾上腺素能反应的个体差异，而缺乏一致的射血前期相关性可能是由于方法学的差异。结果基本上支持心血管反应性稳定的假设。
The temporal stability of cardiovascular reactivity to laboratory stressors over a 2 1/2 yr period was studied. Subjects who had earlier received a cold pressor and a shock avoidance reaction time task were brought back for retesting using almost identical tasks. Cardiovascular variables that were common to both sessions included heart rate, systolic and diastolic blood pressure, and pre-ejection period. Correlations were computed to examine the association of responses across both sessions for the four cardiovascular variables during rest and the two tasks. Correlations of both heart rate and systolic blood pressure were high for all tasks and rest, whereas inconsistent correlations were found for diastolic pressure and pre-ejection period. Inconsistencies in diastolic pressure are speculated to be due to individual differences in beta-adrenergic response, whereas lack of consistent pre-ejection period associations may be due to differences in methodology. The results generally support the assumption of stability of cardiovascular reactivity.
