不少高血压、心脏病患者的家里购置了血压计,进行家庭监护。但常常有患者反映,自己在家用电子血压计测的数值,与医生在医院测的不一致,有时甚至相差很远,不知道为什么。电子血压计测出来的血压值是一种“计算”的结果。电子血压计在增加静压的过程中,提取脉动压并描绘与其相对应的曲线(包络线),对曲线的几何形态加以分析,曲线最高点所对应的静压即为平均压。再由平 Many high blood pressure, heart disease patients purchased a sphygmomanometer at home, for family custody. However, patients often reflect the value of their own home electronic sphygmomanometer, and the doctor at the hospital inconsistency measured, and sometimes even a long way to go, do not know why. The blood pressure measured by an electronic sphygmomanometer is the result of a “calculation”. In the process of increasing static pressure, the electronic blood pressure meter extracts the pulse pressure and depict the corresponding curve (envelope), and analyzes the geometry of the curve. The static pressure corresponding to the highest point of the curve is the average pressure. Then by the level
