This study describes correlations between the mean daily blood pressures determined by ambulatory blood pressure monitoring and those obtained during psychophysiologic stress testing. Seven normotensive and 21 hypertensive persons were monitored for hemodynamic changes in the laboratory while undergoing various standardized, low-challenge psychophysiologic tests. The same persons then had their blood pressure monitored with an ambulatory unit for the rest of the day. The laboratory "resting" pressure used was derived by averaging measurements for mean blood pressure obtained in three positions: standing, sitting, and supine. The "stress" pressure used was the mean blood pressure obtained by averaging three readings taken during videogame playing. A good correlation (r = 0.78) between work-time blood pressure and the laboratory stress pressure was noted. The correlation was improved (r = 0.8) when the averages of laboratory resting and stress values were used. A relationship was also noted between peak pressures obtained during the laboratory testing and those obtained during work-time by ambulatory monitoring.
本研究描述了动态血压监测所测定的平均每日血压与心理生理应激测试期间所测得的血压之间的相关性。对7名血压正常者和21名高血压患者在实验室接受各种标准化、低挑战性心理生理测试时的血流动力学变化进行了监测。然后让这些人在当天剩余时间使用动态血压监测仪监测血压。所采用的实验室“静息”血压是通过对站立、坐立和仰卧三种体位所测得的平均血压进行平均得出的。所采用的“应激”血压是通过对玩电子游戏期间所获取的三次读数进行平均得出的平均血压。研究发现工作时段血压与实验室应激血压之间存在良好的相关性（r = 0.78）。当使用实验室静息值与应激值的平均值时，相关性有所改善（r = 0.8）。研究还发现实验室测试期间所测得的峰值血压与工作时段动态监测所测得的峰值血压之间存在关联。
