Abstract:
Unsmooth pulse is one of the most important pulses in TCM diagnostics. We constructed the wave intensity (WI) images of unsmooth pulse based on the pressure wave ( P ), flow velocity wave ( U ), and WI [ ( d P / d t ) ( d U / d t ) ] by ALOKA Prosound α 10 Color Doppler. The characteristic of Cunkou normal pulse could be summarized as follows: compared to Renying pulse, its W 1 amplitude is smaller and NA wave is more obvious, while the W 2 wave is indistinct or even invisible, and the R -1st is longer than that of Renying pulse. The principal U wave of Renying pulse looks like “Λ” shape, while it looks like an arched blunt “ ∩ ” shape in Cunkou pulse, and the amplitude of U wave in Cunkou pulse is smaller. The direction of the principal U wave in Cunkou unsmooth pulse is up, which shows hoof boots “h” shape with high amplitude and a significant notch on declined branch; the amplitude of predicrotic wave in unsmooth pulse P wave is significantly higher, which could be even higher than that of h1, resulting in early appearance of h3 or integrating with h1, which forms a wide and blunt peak. Unsmooth pulse shows poorer vascular elasticity and greater vascular stiffness.
