本研究探讨了心血管反应性测试中基线测量的几个问题：基线压力的预期影响，初始基线稳定的点，压力任务对后续基线的影响，以及基线模式的性别差异。10名男性和10名女性坐在30分钟的初始基线期，2分钟的压力（心算），和15分钟的压力后阶段。另外10名男性和10名女性仅参与了30分钟的初始基线（无应激源）。有压力和无压力条件之间的初始基线没有差异，也没有这个因素和性别之间的相互作用。大约1分钟后，初始基线稳定在静息水平。应激后的休息水平显著高于血压的初始基线水平（收缩压和舒张压分别为5.8和4.8 mmHg），但心率没有。基线恢复的影响进行了讨论。
This study examined several issues concerning baseline measurement in cardiovascular reactivity testing: effects of anticipation of stress on baseline, point at which initial baseline stabilizes, effects of a stressful task on a succeeding baseline, and gender differences in baseline patterns. Ten males and ten females sat for a 30-min initial baseline period, a 2-min stressor (mental arithmetic), and a 15-min post-stress period. An additional ten males and ten females participated only in the 30-min initial baseline (no stressor). There was no difference in initial baseline between the stress and no-stress conditions; nor were there interactions between this factor and gender. Initial baseline stabilized at resting levels after approximately one minute. Post-stress rest levels were significantly higher than initial baseline levels for blood pressure (5.8 and 4.8 mmHg for systolic and diastolic pressure, respectively), but not for heart rate. Implications of recovery of baseline are discussed.
