Measurements of systolic (SBP) and diastolic (DBP) blood pressure were made at rest and during symptom-limited exercise with an automated blood pressure measuring device (EBPM). Comparisons were made between the EBPM readings and those made with mercury manometer. Correlations were high (SBP r = 0.92, DBP r = 0.80) when readings were made in the same arm, but were less satisfactory when the cuffs were on different arms (SBP r = 0.80, DBP r = 0.46). The correlation between two mercury manometer readings was SBP r = 0.90, and DBP r = 0.75. Comparison between EBPM and intra-arterial measurements were similar (SBP r = 0.74, DBP r = 0.79) to comparison between mercury manometer and intra-arterial measurements (SBP r = 0.81, DBP r = 0.61). The EBPM detected SBP at consistently higher levels than did physicians, which may be an advantage in the noisy environment of an exercise test. There was a definite tendency for physicians to record blood pressure to the nearest 10 mm Hg, whereas the frequency distribution curve for EBPM measurements was smoother. The EBPM operated satisfactorily at rest and during maximal exercise and gave as reliable measurements as a physician using a mercury manometer and, in the small number of available cases, detected exertional hypotension more often than the physician.
使用自动血压测量装置（EBPM）在静息状态和症状限制运动期间测量收缩压（SBP）和舒张压（DBP）。对EBPM的读数与使用汞柱式血压计的读数进行了比较。当在同一手臂测量时相关性很高（SBP r = 0.92，DBP r = 0.80），但当袖带置于不同手臂时相关性则不太理想（SBP r = 0.80，DBP r = 0.46）。两次汞柱式血压计读数之间的相关性为SBP r = 0.90，DBP r = 0.75。EBPM与动脉内测量之间的比较（SBP r = 0.74，DBP r = 0.79）与汞柱式血压计和动脉内测量之间的比较（SBP r = 0.81，DBP r = 0.61）相似。EBPM检测到的SBP水平始终高于医生检测到的水平，这在运动测试的嘈杂环境中可能是一个优势。医生有明确的倾向将血压记录到最接近的10 mmHg，而EBPM测量的频率分布曲线则更平滑。EBPM在静息状态和最大运动期间运行良好，其测量结果与使用汞柱式血压计的医生一样可靠，并且在少数可用病例中，比医生更频繁地检测到运动性低血压。
