TCM Pulse Diagnosis: A Practical, Step-by-Step Guide for Clinicians

TCM pulse diagnosis is one of the oldest skills in clinical practice — and one of the hardest to perform consistently. Two clinicians can press the same wrist and write down different things. This guide gives physicians, acupuncturists and other health professionals a practical, reproducible way to examine and record the radial pulse in Traditional Chinese Medicine (TCM), with biomedical safety built in. It condenses the Professional Manual: Pulse Assessment in TCM (v1.8) written by the KDoctor Technical Team, which follows the Chinese national standard GB/T 40665.4-2021 and the WHO's 2022 standard TCM terminology.

One principle runs through every step: record what you can count before what you interpret, and let biomedical red flags interrupt the TCM reading. The whole exam takes about three minutes for both wrists.

Before you start: is the patient well?

If the patient is pale, sweaty or confused, has fainted, does not respond, or has no pulse at either wrist, this is not the moment for a TCM pulse reading. Stop and check responsiveness, breathing, carotid pulse and blood pressure. If the patient does not respond and is not breathing normally, call emergency services (SAMU 192 in Brazil) and start CPR within your training. If they respond but have low blood pressure or signs of poor perfusion, refer them urgently.

Step 1 — Prepare the patient and yourself

• About 5 minutes of rest in a calm room. Never palpate right after exercise or a strong emotion.
• Position: seated upright or lying on the back, forearm extended at roughly heart level, wrist straight, palm up, resting on a small pulse cushion. If the patient is semi-reclined in bed, stand beside them and support the wrist in your own palm.
• Remove anything that compresses the arm: watch, bag strap, tight cuff.
• Note what changes the pulse: the time; exercise in the last 90 minutes; coffee, alcohol, smoking or a meal in the last 30 minutes; drugs that slow the heart (beta-blockers, verapamil, diltiazem, digoxin, ivabradine, clonidine, antiarrhythmics) or speed it up (salbutamol, theophylline, levothyroxine, decongestants); pregnancy and menstrual phase.
• You: warm hands, short nails, calm breathing — and no conversation or history-taking while you palpate.

Step 2 — Locate the three positions: Cùn, Guān and Chǐ

The wrist pulse lies just behind the wrist crease, on the inner side of the radial styloid process — the bony prominence of the wrist. It is divided into three adjacent positions:

1. Middle position (Guān): level with the bony prominence. Place your middle finger here first.
2. Distal position (Cùn): towards the hand, under your index finger.
3. Proximal position (Chǐ): towards the elbow, under your ring finger.

Keep the fingers arched with the tips level, touching with the finger pad at about 45° to the skin. Spread them on tall patients and bring them closer on small ones. Use your right hand on the patient's left wrist and vice versa, and always examine both wrists.

No pulse on one side in a stable patient? Before concluding anything, look for an anatomical variant: an oblique pulse that runs towards the back of the hand, or a pulse on the back of the wrist. A variant only explains the absence if you actually find the pulse there.

Step 3 — Press from light to heavy: together, then one finger at a time

Each position has three depths, always explored from the lightest to the heaviest pressure:

• Superficial (light pressure): between the skin and the vessel;
• Middle (moderate pressure): at the level of the muscle;
• Deep (heavy pressure): between the tendons and the bone.

Start with joint pressure — all three fingers with the same force — to feel what is common to the whole wrist. Then use single pressure, one finger at a time while lifting the others, to find what differs at a single position. Finish by comparing left and right.

Step 4 — Count for 60 seconds on the clock

Count for a full 60 seconds on a watch, at each wrist. If the rate is below 50 per minute, keep counting until you reach 50 beats. Counting against your own breathing is a classical exercise, but a clinician's breathing rate varies, so the clock is what goes on the record. Remember that this is the radial pulse rate: with an irregular rhythm, some beats do not reach the wrist, and the count can be lower than the true heart rate.

In KDoctor the raw bpm is the primary data, and the TCM category is derived from it:

Don't confuse Racing (疾 jí), a rate category, with Skipping (促 cù), an irregular pulse. And Moderate (缓 huǎn) is a quality, not a rate band.

Step 5 — Assess the eight elements of TCM pulse diagnosis

The Chinese national standard defines eight elements of the pulse exam. Recording each one separately is what makes the exam reproducible:

Also record left–right symmetry: equal, different (which side is weaker) or absent.

Step 6 — Judge stomach qi, spirit and root together

These are the three marks of a healthy pulse. Mark each one as present, diminished, absent or not assessable:

• Stomach qi (胃 wèi): with three fingers at medium pressure, the pulse comes and goes relaxed, moderate and smooth.
• Spirit (神 shén): soft yet forceful, with a regular rhythm. Strength alone is not spirit.
• Root (根 gēn): pressing down to the deep level at the proximal (Chǐ) positions, the pulse keeps beating with some force.

Use diminished when the mark is there but reduced, and not assessable when you could not examine or decide — oedema, obesity, tremor, agitation — and write down why. Mark absent only when the finding is unequivocal on a second palpation: an absent mark is a red flag.

Step 7 — Name the pulse: up to three qualities

The pulse name summarises the elements you have already recorded; it does not replace them. Choose from the 28 classical pulses and follow a few rules:

• Up to three qualities per wrist. This is a KDoctor convention; in the literature, combinations of two or three are the norm.
• Never opposite poles, such as Floating with Deep, Slow with Rapid, Slippery with Rough, Long with Short.
• A compound pulse replaces its parts: deep + thin + forceless is Weak (弱 ruò). Write "Weak", not "Weak, Deep".
• An irregular rhythm always takes a slot: Skipping (促 cù), Knotted (结 jié) or Intermittent (代 dài).
• Global first, then positions: record the qualities of the whole wrist and, at each position, only what differs from the global. If nothing differs, mark "= global".
• Nothing altered? Leave the qualities blank, mark the Normal category and the three marks as present.

Illustrative example, not a real case: 56 bpm, regular, deep, thin and forceless at both wrists. Global qualities: Weak, Slow. Stomach qi present; spirit and root diminished; every position "= global". Because the resting rate is below 60, the finding is also communicated to the responsible clinician in the same visit.

Step 8 — Record where you felt it, not the organ

Classical authors share a common base for the position–organ map — heart, liver and kidney on the left; lung, spleen and kidney on the right — but disagree on the rest, and no systematic review has validated the correspondence. So record the location of the finding: side × position × depth, and leave the organ attribution for later, with the school declared. Close the record with your confidence (high, medium or low) and the factors that got in the way. This is the minimum record our Technical Team defined for KDoctor: closed lists, plain-language names and the Chinese term kept as a code behind each choice.

Red flags: when biomedical care comes first

A TCM pulse exam does not rule out cardiovascular disease. These findings interrupt the TCM reading until a biomedical assessment is done or arranged:

The 2025 Brazilian Atrial Fibrillation Guideline describes opportunistic screening by pulse palpation or ECG during routine care, especially from age 65, and requires an ECG recording of at least 30 seconds to diagnose AF (Arq Bras Cardiol, 2025). One rule has no exceptions: never change medication based on a TCM pulse reading.

What the evidence supports — and what it doesn't

A systematic narrative review of 12 studies found limited evidence on the reliability of manual pulse diagnosis, but acceptable intra- and inter-rater reliability when the methods were operationally defined; poor agreement was linked to vague terminology (Bilton & Zaslawski, 2016). That is the logic of this guide: a closed vocabulary, counted data first, explicit confidence. It is the same gap we described in Chinese Medicine standardized the vocabulary — but not the reasoning. And remember that the pulse is only part of palpation, which is one of the four examinations: never base a conclusion on the pulse alone.

Who may perform it in Brazil

Law No. 15,345 of 12 January 2026 regulates the practice of acupuncture in Brazil. Among others, it guarantees practice to university-level health professionals holding a specialist title in acupuncture recognised by their federal council, and it allows other health professions to use isolated acupuncture procedures within the rules of their councils, after a specific extension course (Agência Senado, 2026). This guide standardises technique and record-keeping; it does not define or extend anyone's professional scope. Check your council's rules.

From the wrist to a structured record

A careful pulse exam takes about three minutes; a good record lasts much longer. KDoctor's AI agents offer TCM pattern hypotheses linked to classical sources for your evaluation — never in place of your judgment. See how the KDoctor TCM module works.
