摘　　要：流行病学调查及大规模前瞻性研究表明,高血压是心血管疾病的独立风险因素,采用电子血压计进行自助式日常血压监护,是预防严重心血管事件的重要途径。提出了一种设计电子血压计的新方法:首先确定振荡波中各个单波的峰值点;然后确定拟合振荡波包络线的最佳拟合曲线;进而查找包络线的最大值,选定积分区间,提出的积分公式和最大值的位置,确定舒张压和收缩压的位置,最后确定舒张压和收缩压。比较该方法与听诊法测得的血压,结果证明使用所介绍的方法测得的血压精度符合AAM I标准、BHS(B)级标准。说明该方法是适用的,使用该方法所设计的电子血压计可以用于血压的日常监护。Epidemiological investigation and large scale prospective study shows that hypertension is an independent risk factor for cardiovascular disease.The daily blood pressure self-monitoring by using electronic BP monitor is an important way to prevent serious cardiovascular events.A new method for designing electronic BP monitor is proposed： firstly,determine the single-wave＇s peak points of Sasser;secondly,determine the best fitting curve and fit the contour line of Sasser;then,find maximum of the contour line,select integration interval and determine the location of DBP and SBP by the proposed integral formula and the location of the maximum,and finally determine DBP and SBP.Compared BP measured by the proposed method and auscultation,results show that BP measured by the proposed method has an accuracy consistent with AAMI standard and BHS（B） standard.So the proposed method is applicable,electronic BP monitor designed by using the proposed method can be used to monitor BP daily.
