The volume of blood flow (F), its velocity (V) and the internal diameter (D) of patients with uneven pulse (PUP) were determined and compared with control.
The F, V and D of PUP were significantly less than those of control respectively (P < 0.001). It provided objective basis for Blood Stasis. Furthermore, the value of spectrum of tongue of PUP were measured. Values of red and orange ray of PUP were less, while those of green and blue ray were more than those of normal subjects respectively. The value of purple ray were negative correlated with F and V. The values of red and orange ray were correlated with F and V. It revealed that uneven pulse and purple tongue existed simultaneously in majority. Combination of the two signs was in favour of the diagnosis of blood Stasis.
测定了脉象不匀患者的血流量（F）、血流速度（V）和内径（D），并与对照组进行比较。
脉象不匀患者的F、V和D分别显著低于对照组（P < 0.001）。这为血瘀提供了客观依据。此外，还测量了脉象不匀患者的舌光谱值。脉象不匀患者的红、橙光值较低，而绿、蓝光值分别高于正常受试者。紫光值与F和V呈负相关。红、橙光值与F和V相关。结果显示，多数患者脉象不匀与紫舌同时存在。两种体征的结合有利于血瘀的诊断。
