The Construction of Unsmooth Pulse Images in Traditional Chinese Medicine Based on Wave Intensity Technology

الملخص EN

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 [(dP/dt)(dU/dt)] by ALOKA Prosound α 10 Color Doppler.

The characteristic of Cunkou normal pulse could be summarized as follows: compared to Renying pulse, its W1 amplitude is smaller and NA wave is more obvious, while the W2 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.
