The effects of high ambient stressors (equipment sounds) and social stressors (conversation) on heart rate (HR) and blood pressure (BP) were examined in coronary care patients. Simultaneously occurring sound level in decibels, actual sound, electrocardiogram, and BP were recorded three times/day over 2 days for 20 subjects. Repeated measures ANOVA and pairwise comparisons revealed maximum HR to be significantly higher during conversation than during low ambient sounds (quiet). High ambient stressors did not affect HR for these subjects. BP did not significantly change during any of the sound conditions. Further research is needed to delineate cardiovascular effects of specific social stressors.
在冠心病监护病房患者中，研究了高环境应激源（设备声音）和社会应激源（交谈）对心率（HR）和血压（BP）的影响。对20名受试者在2天内每天3次记录以分贝为单位的同时出现的声音水平、实际声音、心电图和血压。重复测量方差分析和成对比较显示，交谈期间的最高心率显著高于低环境声音（安静）期间。高环境应激源对这些受试者的心率没有影响。在任何声音条件下，血压均无显著变化。需要进一步研究以阐明特定社会应激源对心血管的影响。
