目的比较Hartmann-Rico公司生产的水银血压计和电子仪器Tensoval Duo Control同时测量心房颤动患者血压的准确性。材料和方法在5个诊所对255例患者进行两次同时测量，测量间隔至少为3min。在整个患者组中，通过考虑患者的性别和年龄并使用标准或更大的袖带，在多个水平上使用配对t检验进行测量精度分析。两种方法在绝对值上的差异被归类为四个频段之一(<；5、<；10、<；15 mm Hg及以上)。结果在血压方面，水银仪与Duo控制仪的测量值平均相差0.1 mm Hg[标准差=4.7(无统计学意义)]。对于舒张压，测量值的差异平均为-0.7毫米汞柱[标准差=4.7，P<；0.05]。使用DUO对照组测得的舒张压平均比使用汞血压计测得的值高0.7毫米汞柱，而在使用标准袖带的亚组中，两者的差值平均为-1.1毫米汞。与性别、年龄、参与诊所的地点和脉搏值高于或低于60次/分相关的子分析没有显示出显著差异。结论使用具有双重测量控制的电子设备测量血压，即使在绝对心律失常的情况下，如房颤，也能提供准确的结果。舒张压的最小差值在临床上是不显著的。血液出版社Monit 16：252-257(C)2011 Wolters Kluwer Health|Lippincott Williams&Wilkins。
Aim The aim of our study was to compare the accuracy of blood pressure measurements in patients with atrial fibrillation using simultaneous measurements by a mercury sphygmomanometer and an electronic device Tensoval duo control, produced by Hartmann-Rico, with dual control of the measurements (oscillometric and auscultation).Materials and methods A total of 255 patients were examined at five clinics using two simultaneous measurements with a time interval of at least 3 min. The measurement accuracy analysis was carried out using a paired t-test, at several levels, throughout the whole group of patients, by considering the patient's sex and age and using a standard or larger cuff. Differences between both methods in absolute values were categorized into one of four bands (< 5, < 10, < 15mmHg and more). Analyses according to the location of participating clinics and higher versus lower pulse rate during examination were also carried out.Results For systolic blood pressure, the difference of the measured values between the mercury and duo control device was on average 0.1mmHg [standard deviation = 4.7 (not significant)]. For diastolic blood pressure, the difference in measured values was on average -0.7mmHg [standard deviation = 4.7, P < 0.05]. The values of diastolic blood pressure measured using duo control were on average 0.7 mmHg higher than the values measured using the mercury sphygmomanometer, whereas in the subgroup using the standard cuff the difference was on average -1.1 mmHg. Subanalyses related to sex, age, location of participating clinics and pulse value higher or lower than 60bpm did not reveal significant differences.Conclusion Measuring blood pressure using an electronic device with a dual control of measurement provides accurate results even in the case of absolute arrhythmia, such as atrial fibrillation. Minimum differences in the values of diastolic blood pressure are clinically insignificant. Blood Press Monit 16: 252-257 (C) 2011 Wolters Kluwer Health | Lippincott Williams & Wilkins.
