Also known as: A V Block, Heart Block
While a pacemaker corrects the electrical delay, TCM works to restore the Heart's own rhythm by warming deficient Yang, nourishing depleted Blood, or clearing obstructing Phlegm - and many patients notice their palpitations lessen within weeks of starting herbs and acupuncture.

Atrioventricular (AV) block - also called heart block - is a condition where the heart's electrical signals are delayed or blocked, often causing palpitations, dizziness, or fatigue. In Traditional Chinese Medicine, this falls under the category of 'palpitations' (心悸, xīn jì), which is not a single disease but a symptom that can arise from six distinct patterns. Each pattern involves a different root imbalance, from a weakened Heart Yang that fails to power the beat, to phlegm-fire agitating the Heart's rhythm. This page explains how TCM understands and treats palpitations and AV block by addressing the underlying cause, not just the electrical delay.
The heart's rhythm is controlled by electrical impulses that travel from the atria to the ventricles through the atrioventricular node. In AV block, these signals are delayed or completely blocked, leading to a slow or irregular heartbeat. First-degree AV block is usually harmless; second-degree causes occasional dropped beats; third-degree (complete heart block) can cause severe bradycardia, fainting, and requires a pacemaker. Diagnosis is made by electrocardiogram (ECG).
Conventional treatments
Mild AV block often requires no treatment beyond monitoring. For symptomatic bradycardia, a pacemaker is the definitive treatment, especially for second-degree type II and third-degree block. In emergencies, atropine or temporary pacing may be used. There are no medications that reliably restore normal conduction long-term.
Where conventional treatment falls short
A pacemaker effectively prevents dangerous pauses but does not address the fatigue, cold intolerance, palpitations, or anxiety that often accompany heart block. Many patients with mild or intermittent block are told to wait and watch, leaving them without relief from distressing symptoms. Conventional medicine also treats all AV block as a structural electrical problem, without considering whether the root lies in a deficiency of warming Yang, a lack of nourishing Blood, or an accumulation of phlegm-dampness - distinctions that TCM uses to guide treatment and potentially improve overall heart function.
How TCM understands atrioventricular block
In TCM, the Heart is not just a pump - it houses the Shen (Spirit), the consciousness that gives us a sense of peace and steady rhythm. A normal heartbeat depends on the Heart receiving sufficient Qi and Blood to anchor the Shen, and enough Yang to drive the beat. When any of these are deficient, or when pathogenic factors like phlegm, fire, water, or blood stasis obstruct the Heart, the rhythm becomes unsteady, producing palpitations (心悸).
This is why AV block, from a TCM perspective, is not a single disease but a symptom that can stem from very different root imbalances.
A TCM practitioner listens carefully to the quality of the heartbeat - is it slow and weak, rapid and thin, or forceful and irregular? They then ask about accompanying sensations: cold limbs, fatigue, night sweats, irritability, swelling. The tongue's color and coating, along with the pulse's speed, strength, and rhythm, provide the final confirmation.
For example, a pale, puffy tongue with a deep, slow pulse points to Heart Yang Deficiency, where the heart lacks warmth to drive the beat. A red tongue with little coating and a thin, rapid pulse suggests Heart Yin Deficiency, where cooling Yin is too weak to anchor the rhythm. A thick, yellow tongue coating with a slippery, rapid pulse indicates Phlegm-Fire harassing the Heart.
The Heart does not work alone. The Spleen produces the Blood that nourishes the Heart; the Kidneys provide the foundational Yin and Yang that warm or cool the Heart; the Liver ensures smooth Qi flow so Blood can circulate.
A Spleen weakened by overwork or poor diet fails to generate enough Blood, leading to palpitations with fatigue and poor appetite (Heart and Spleen Qi and Blood Deficiency). When Kidney Yang is weak, water metabolism fails, and retained fluids surge upward to oppress the Heart, causing a pounding sensation and swelling (Water Qi intimidating the Heart). Thus, AV block often reflects a deeper systemic imbalance that TCM traces back to these organ systems.
Because the same Western diagnosis can have multiple TCM causes, treatment is highly individualized. A person with cold hands and feet and a slow pulse needs warming Yang herbs, while someone with night sweats and a rapid pulse needs nourishing Yin. This is why TCM can offer relief even when conventional options are limited - by restoring the body's own ability to maintain a steady rhythm.
「火逆下之，因烧针烦躁者，桂枝甘草龙骨牡蛎汤主之。」
"When fire therapy is wrongly applied and purgation follows, causing vexation and agitation due to the burning needle, Gui Zhi Gan Cao Long Gu Mu Li Tang governs it. This clause describes a pattern of injured Heart Yang leading to palpitations and restlessness, treated by warming and settling the Heart."
How a TCM practitioner diagnoses atrioventricular block
Inside the consultation
A TCM practitioner starts by listening carefully to the quality of the heartbeat-whether it feels like a flutter, a pause, a forceful pound, or a slow, heavy thud. They then ask about accompanying sensations: fatigue, cold limbs, night sweats, or irritability. The tongue’s color and coating, along with the pulse’s speed, strength, and rhythm, provide the final confirmation of which pattern is causing the AV block.
If the palpitations come with overwhelming fatigue, poor appetite, and a pale, washed-out complexion, the root is often Heart and Spleen Qi and Blood Deficiency. The tongue looks pale with a thin white coat, and the pulse feels weak and thin. This pattern reflects the Spleen’s inability to produce enough Blood to anchor the Heart, leaving the heartbeat unsteady and easily triggered by exertion or worry.
When the heartbeat is rapid and accompanied by a restless mind, dry mouth at night, and a feeling of heat in the palms and soles, Heart Yin Deficiency is likely. The tongue appears red with little or no coating, and the pulse is thin and rapid. Here, the cooling, anchoring Yin is too weak to hold the Heart’s spirit, so the rhythm speeds up and sleep becomes shallow.
A slow, deep, or intermittent heartbeat that worsens with cold and is paired with chilly hands and feet points to Heart Yang Deficiency. The tongue is pale and puffy, and the pulse is deep, slow, and weak. In this pattern, the Heart’s warming, pushing force has dimmed, much like a furnace running low, causing the electrical signal to slow and the chest to feel oppressed.
If the palpitations are forceful and paired with a bitter taste, chest fullness, and a short temper, Phlegm-Fire may be harassing the Heart. The tongue is red with a thick, yellow, greasy coat, and the pulse is slippery and rapid. This pattern is like sticky, heated phlegm clouding the Heart’s chamber, triggering erratic beats and a sense of inner agitation.
TCM Patterns for Atrioventricular Block
In TCM, the aim is to address the root cause, not just the symptom — it calls that root cause a “pattern.” The same atrioventricular block can come from several different patterns, each treated differently. The quickest way to find yours is the quiz below.
Find your pattern
Tap any sign that fits how yours feels.
- 1Your signs
- 2What makes it worse
- 3What helps
Which signs match your experience?
It is very common to see a blend of these patterns rather than a pure single type. For example, someone with long-standing fatigue and pale complexion (Qi and Blood Deficiency) may also develop night sweats and a rapid pulse (Yin Deficiency), because the body’s fluids and Blood are intertwined. Similarly, a person with a slow, cold-type palpitation (Yang Deficiency) might also have swelling or a heavy sensation (Water Qi), since weakened Yang fails to move fluids.
When your symptoms seem to cross several categories, pay attention to which feature is most dominant and what makes it better or worse. A heartbeat that calms with rest and worsens with stress often leans toward a deficiency pattern, while one that feels better with cooling foods and worse with rich, greasy meals suggests Phlegm-Fire involvement. The tongue and pulse remain the most reliable guides, which is why a professional assessment is invaluable.
Because AV block can range from a mild skipped beat to a serious electrical delay, any sudden worsening, chest pain, fainting, or severe breathlessness should be evaluated by a medical doctor promptly. A TCM practitioner can work alongside your cardiologist to support your overall vitality and rhythm, but never delay emergency care when the heart’s function is acutely compromised.
If your self-assessment is mixed, a TCM practitioner will take a full history, examine your tongue and pulse, and often detect subtle signs that clarify the underlying pattern. With that clarity, they can design a personalized treatment using herbs, acupuncture, and dietary advice to gently rebalance the system. This is especially helpful when the palpitations are persistent but not immediately dangerous.

Four ways to address atrioventricular block in TCM — explore each, or take the quiz to see what fits you first.
Formulas traditionally used for atrioventricular block
6 formulas across the patterns above. The right one depends on your pattern — start with the quiz if you're unsure which fits.
A classical formula that strengthens the Spleen and nourishes the Heart to address fatigue, poor appetite, insomnia, forgetfulness, palpitations, and anxiety caused by weakness of both the Heart and Spleen. It is also widely used for bleeding disorders such as heavy or prolonged menstrual periods, easy bruising, or blood in the stool that result from the Spleen being too weak to keep blood in its proper channels.
A classical formula for people who have trouble sleeping and feel restless due to overwork or prolonged mental exertion. It nourishes the body's Yin and Blood while calming the mind and clearing low-grade internal heat. Often used for insomnia with palpitations, forgetfulness, night sweats, and a general sense of mental exhaustion.
A classical formula used to clear Heat and resolve Phlegm that is disturbing the mind and digestive system. It is commonly used for insomnia, restlessness, nausea, and a bitter taste in the mouth caused by the accumulation of Phlegm-Heat in the Gallbladder and Stomach. Think of it as a formula that calms both an agitated mind and an upset stomach by addressing the underlying combination of inflammatory Heat and sticky Phlegm.
A classical formula for people who feel persistently cold, experience swelling or puffiness (especially in the legs), have reduced urine output, and may suffer from dizziness, loose stools, or palpitations. These symptoms arise when the body's warming energy is too weak to properly manage fluids, causing water to accumulate where it shouldn't. Zhen Wu Tang warms the body's core while gently helping it drain excess fluid through urination.
A classical four-herb formula used to address dizziness, heart palpitations, chest fullness, and shortness of breath caused by a weak digestive system failing to properly process fluids. It gently warms the body and helps move excess fluid accumulation, particularly when someone feels heavy, waterlogged, or dizzy upon standing.
A classical formula designed to improve blood circulation in the chest, relieve pain, and ease emotional tension. It is widely used for chronic chest pain, stubborn headaches, insomnia, and irritability caused by poor blood flow and stagnation in the upper body.
For excess patterns like Phlegm-Fire or Blood Stagnation, palpitations often improve within 4-8 weeks of treatment. Deficiency patterns - Heart Yang Deficiency, Qi and Blood Deficiency, or Yin Deficiency - require rebuilding the body's reserves, so consistent treatment for 3-6 months is typical. Acupuncture is usually given weekly, while herbal formulas are taken daily. Even after symptoms improve, a maintenance phase may be recommended to prevent recurrence.
Treatment principles
All TCM treatments for palpitations aim to calm the Shen (spirit) and stabilize the Heart's rhythm. However, the method varies: warming Yang for cold patterns, nourishing Blood and Qi for deficiency patterns, clearing Phlegm-Fire for excess patterns, and moving Blood for stasis. Many patients present with mixed patterns, so formulas are often customized to address both the root and the branch. Acupuncture points like Neiguan (PC-6) and Shenmen (HT-7) are used across patterns to regulate the heartbeat, while additional points target the specific underlying imbalance.
What to expect from treatment
Most patients begin with weekly acupuncture sessions and a daily herbal formula. Improvement in palpitations is often noticeable within 3-6 weeks, but complete resolution of deeper deficiency may take 3-6 months. You may first notice better sleep and less anxiety, followed by a steadier heartbeat. Your practitioner will adjust the formula as your symptoms change. Consistency is key - skipping doses or missing appointments can slow progress.
General dietary guidance
In general, eat warm, cooked meals that are easy to digest to support the Spleen and Heart. Avoid cold, raw foods and icy drinks, which can weaken digestion and promote phlegm-dampness. Minimize caffeine, alcohol, and spicy, greasy foods, as they can aggravate Phlegm-Fire or deplete Yin. Beneficial foods include longan fruit (Long Yan Rou) to nourish Heart Blood, jujube dates (Da Zao) to tonify Qi, and lotus seed (Lian Zi) to calm the Shen. Your practitioner will tailor dietary advice to your specific pattern.
Combining TCM with conventional treatment
TCM can safely complement conventional management of AV block. If you have a pacemaker, acupuncture and most herbs are not contraindicated, but always inform both your cardiologist and TCM practitioner. Certain herbs, such as licorice (Gan Cao), may affect electrolyte balance and blood pressure, so monitoring is important.
Herbs that move Blood (like Dang Gui, Chuan Xiong) could interact with anticoagulants, so close coordination is needed. Never stop or adjust prescribed heart medications without consulting your doctor. A collaborative approach ensures the best outcomes.

Safety & special considerations
-
Fainting or loss of consciousness — May indicate a dangerous drop in heart rate and requires immediate evaluation.
-
Severe chest pain or pressure — Could be a sign of a heart attack or other cardiac emergency.
-
Sudden shortness of breath — Especially if it occurs at rest or with minimal activity, it may signal a serious rhythm disturbance.
-
Heart rate very slow (below 40 bpm) or very fast (above 100 bpm at rest) — Extreme bradycardia or tachycardia can compromise circulation.
-
Palpitations with dizziness, confusion, or cold sweat — These could indicate that the heart is not pumping enough blood to the brain.
-
New or worsening swelling in the legs or ankles — Could be a sign of heart failure, especially if accompanied by shortness of breath.
Audience-specific guidance — open what applies to you
During pregnancy, Heart Blood and Yin Deficiency patterns become more prominent because the growing fetus draws heavily on the mother's Blood and essence. Palpitations often worsen in the second and third trimesters, accompanied by fatigue, dizziness, and a pale tongue. Gui Pi Tang is a gentle, nourishing formula that can be used with caution, but Mu Xiang should be reduced or omitted, and Dang Gui is generally safe in moderate amounts under professional guidance.
Formulas that strongly move Blood, such as Xue Fu Zhu Yu Tang, are contraindicated in pregnancy. Bitter-cold herbs like Huang Lian should be avoided or used sparingly. Acupuncture is an excellent alternative, especially in the first trimester; points like Neiguan PC-6 and Shenmen HT-7 are safe and effective, while points on the lower abdomen and strong moving points like Hegu LI-4 should be avoided.
Most gentle, nourishing formulas like Gui Pi Tang are compatible with breastfeeding and may even support milk production by strengthening the Spleen and Blood. However, strong bitter-cold herbs such as Huang Lian can pass into breast milk and cause infant diarrhoea or digestive upset, so they should be avoided or replaced with milder alternatives like Zhu Ye if heat-clearing is needed.
Acupuncture remains a safe and effective option during breastfeeding. Needling points like Neiguan PC-6, Zusanli ST-36, and Sanyinjiao SP-6 can regulate the heart rhythm without any risk to the infant. If herbal medicine is used, it is wise to take the formula immediately after nursing to minimise the amount reaching the baby.
Atrioventricular block is uncommon in children, but when palpitations occur they often stem from a weak Spleen and Heart Qi, or from Phlegm-Fire harassing the Heart after febrile illnesses. Children cannot easily describe a fluttering or skipped beat, so diagnosis relies on observing pallor, fatigue, irritability, and a pulse that may be irregular or rapid. Herbal dosages are typically one-quarter to one-half of the adult dose, adjusted by age and weight.
Gentle formulas like Gui Pi Tang in reduced doses are suitable for Heart-Spleen Deficiency. For post-viral Phlegm-Fire, a mild version of Huang Lian Wen Dan Tang may be used, but bitter herbs should be minimised. Acupuncture is well tolerated, and non-needle techniques like acupressure on Neiguan PC-6 can be taught to parents for home care.
In older adults, deficiency patterns dominate - particularly Heart Yang Deficiency and Heart and Spleen Qi and Blood Deficiency. The pulse is often deep, slow, and knotted, and the tongue is pale and puffy. Treatment timelines are longer, and herbal dosages should generally be two-thirds of the standard adult dose to avoid burdening a weakened Spleen. Polypharmacy is a concern, so herbal formulas must be screened for interactions with cardiac medications like digoxin or beta-blockers.
Acupuncture is often better tolerated than herbs in the elderly and carries no drug interaction risk. Points such as Neiguan PC-6, Shenmen HT-7, and Zusanli ST-36 are safe and can be needled with gentle stimulation. Regular, light movement like walking supports Yang circulation, but overexertion should be avoided.
Evidence & references
The evidence base for TCM treatment of atrioventricular block is modest but suggestive. A 2011 systematic review of acupuncture for cardiac arrhythmias found that acupuncture may help regulate heart rate, though the included studies were small and of variable quality. Acupuncture's effect on the autonomic nervous system is a plausible mechanism, and it is generally considered a safe adjunctive therapy.
Chinese herbal medicine studies, largely published in Chinese-language journals, report improvements in palpitation frequency and quality of life for patterns like Heart Yang Deficiency and Heart-Spleen Deficiency. However, few randomised controlled trials have specifically targeted AV block, and English-language research remains limited. Larger, well-designed trials are needed to confirm these findings.
Key clinical studies
This systematic review evaluated the efficacy of acupuncture for various cardiac arrhythmias, including bradyarrhythmias and palpitations. It concluded that acupuncture may offer modest benefits in regulating heart rate, with a favourable safety profile, but highlighted the need for more rigorous trials.

Common questions about using Traditional Chinese Medicine for atrioventricular block.
TCM aims to improve the underlying imbalance causing palpitations; many patients experience fewer skipped beats and less fatigue, but it does not replace a pacemaker if one is medically necessary. It's best used alongside conventional monitoring.
TCM does not reverse structural electrical blocks that require pacing. If your cardiologist recommends a pacemaker, you should follow that advice. TCM can support your overall heart health and reduce symptoms like palpitations and anxiety, but it is not a substitute for life-saving devices.
Many patients notice a reduction in palpitations within 4-6 weeks of consistent herbal and acupuncture treatment. The full effect depends on the pattern - excess patterns respond faster, while deficiency patterns may take several months.
Yes, when performed by a licensed practitioner, acupuncture is generally safe for people with heart rhythm disorders. Needles are placed at specific points that regulate the Heart's rhythm, such as Neiguan (PC-6). Always inform your practitioner and cardiologist about all treatments you are receiving.
Some herbs can interact with medications like beta-blockers, digoxin, or anticoagulants. For example, licorice (Gan Cao) may affect potassium levels and blood pressure. It is essential to provide your TCM practitioner with a complete list of your medications, and to keep your cardiologist informed. Never stop prescribed medications without medical supervision.
Generally, avoid cold, raw foods and icy drinks, which can weaken the digestive fire and contribute to phlegm-dampness. For Heart Yang Deficiency, include warming foods like ginger, cinnamon, and lamb. For Heart Yin Deficiency, emphasize moistening foods like pears, lily bulb, and black sesame. Avoid greasy, spicy, and fried foods if you have Phlegm-Fire. A TCM practitioner can give you specific advice based on your pattern.
