Choppy Pulse / Se Mai
Updated 2026-08-01
INTRODUCTION
English translation pending.
CORE DEFINITION
The choppy pulse is a classical pulse quality described as fine, slow, short and uneven, feeling like a light knife scraping bamboo. It indicates impaired and poorly lubricated blood movement, and is classically associated with depletion of essence and blood, qi stagnation with blood stasis, and damage to fluids. It is distinguished from the knotted and intermittent pulses, which have their own patterns and causes. Like every pulse quality, it is interpreted alongside the full clinical picture rather than in isolation.
SCAFFOLDING EFFECT
Reduce cognitive load
- Friction Reading: roughness in the flow suggests either too little fluid or an obstruction in the channel - Two Causes: separate deficiency from stasis before choosing which treatment to apply - Trend Signal: a pulse that turns smoother over time indicates that flow is improving
Anchor fast decisions
Smooth flow requires adequate volume and an unobstructed channel. A rough uneven pulse arises when either condition fails: too little fluid means the wave cannot fill and transmit evenly, while stasis means the wave must work around obstruction. Because both produce the same tactile quality, the sign establishes that flow is impaired without establishing which cause, so the treatment depends entirely on the accompanying signs.
