[Doppler sphygmogram of uneven pulse and spectral changes of tongue]
Unlabelled:
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.
Results:
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.
