摘要 目的:研究不同误差状态的设置对高血压脉搏波速度(PWV)检测结果的影响。方法和材料:选择270名年龄在46~80岁的健康体检人群,男女各半。分别采用国际上先进的脉搏波速度测定系统Complior仪检测受检人群不同节段的PWV值。颈股CF—PWV、颈挠CR—PWT、颈远端CD—PWV,分别反映主动脉、上肢动脉和下肢动脉的僵硬度。将3组受检人群检测时动态误差在分别设置为15%〉误差〉10%、10%〉误差〉5%、5%〉误差三种状态下,重复测量各节段的PWV值,观察不同误差设置对检测结果的影响。结果:动态误差在10%〉误差〉5%,5%〉误差两种状态下各组人群的各节段PWV值无显著差异;而动态误差在15%〉误差〉10%时,与动态误差〈5%组比较,各节段PWV值的差异显示出统计学意义。结论:动态误差分析系统对PWV检测结果会有不同影响,选择误差较小的检测模式有利于提高检测结果的准确性。检测时只要误差控制在10%以下,对检测结果重复性和可靠性不会产生影响。
