紧脉与弦脉脉图比较

Comparison of Pulse Graphs Between Taut pulse and Viry Pulse

目的探讨紧脉和弦脉两种脉象脉图是否存在差异,寻找两种脉象的客观诊断指标。方法采用脉象仪对紧脉(38例)和弦脉(40例)进行了脉图参数的检测,以35例平脉作为对照组比较。结果紧脉和弦脉主波升支陡峭,脉波上升速度快、斜率大;主波高且宽;重搏前波波幅及高度升高;降中峡高度升高。与平脉比较都具有显著性差异(P<0.001)。与弦脉比较,紧脉重搏前波波幅及降中波波幅增高明显(P<0.01);而主波宽度不如弦脉增加明显(P<0.01)。结论紧脉脉图与弦脉脉图间存在差异。较之弦脉,紧脉外周阻力的加大,更可能是血管功能性收缩增强的结果。

Objective To survey the difference of the pulse graphs of taut pulse and vire pulse and its objective diagnostic indexes. Methods With vire pulse （40 cases） and common pulse（35 cases） , sphygmograph was used to test pulse graph parameters of taut pulse （38 cases）. Results Main wave of taut pulse and vire pulse was steep;pulse wave went up quickly and its slope rate was large. Main wave was high and wide. The amplitude of wave before repeat wave was increased, the height of dicrotic notch was increased, there was obvious difference compared with the control group（ P 〈0. 001 ）. The amplitude of wave before repeat wave and dicrotic wave obviously increased compared with vire pulse（ P 〈 0.01 ）, but its width of main wave didn＇t increase greatly（ P 〈 0.01 ）. Condusion There is difference between the pulse graphs of taut and vire pulse. The peripheral resistance of taut pulse is greater than that of vire pulse, which may be caused by strong functional contraction of blood vessel.
