Abstract

The accuracy and reproducibility of a new automatic device (P) specially designed for noninvasive blood pressure monitoring during the exercise stress test were evaluated in 50 consecutive subjects (34 normotensives and 16 hypertensives). Automatic measurements were compared with those taken by a sphygmomanometer (RR). A good agreement between systolic pressure values obtained by the two methods was found (RR 159 +/- 30 mmHg, P 158 +/- 28 mmHg, mean difference = -1.53 +/- 13 mmHg, p = 0.166, ns). On the contrary the new device significantly underestimated diastolic pressure values (RR 89.3 +/- 13 mmHg; P 84 +/- 13 mmHg, mean difference -5.37 +/- 9.3, p < 0.001). In conclusion the new device seems able to measure systolic but underestimates diastolic blood pressure both in hypertensives and in normotensives during the effort test.

摘要

在50名连续受试者（34名血压正常者和16名高血压患者）中，对一种专门设计用于运动应激试验期间无创血压监测的新型自动装置（P）的准确性和可重复性进行了评估。将自动测量结果与用血压计（RR）测量的结果进行比较。发现两种方法获得的收缩压值之间具有良好的一致性（RR为159±30 mmHg，P为158±28 mmHg，平均差值=-1.53±13 mmHg，p = 0.166，无显著性差异）。相反，新装置显著低估了舒张压值（RR为89.3±13 mmHg；P为84±13 mmHg，平均差值-5.37±9.3，p<0.001）。总之，在运动试验期间，新装置似乎能够测量收缩压，但在高血压患者和血压正常者中均低估了舒张压。
