- Atrial fibrillation is an irregular rhythm arising from the upper chambers of the heart.
- Some people notice racing or fluttering; others discover it during a pulse check or ECG.
- AF can increase stroke risk, so treatment decisions should be based on medical assessment rather than symptoms alone.
Why this deserves attention
Atrial fibrillation may feel like palpitations—or cause no obvious symptoms. An irregular pulse, breathlessness or unexplained fatigue should be medically checked.
The same symptom can have several causes. Useful clues include how quickly it changed, how severe it is, what comes with it, personal risk factors and whether it is clearly different from your normal baseline.
What to observe
If you notice an irregular pulse, record time, duration, resting heart rate, associated dizziness or breathlessness, caffeine/alcohol intake and any new medicines.
Write down when symptoms happen, how long they last, triggers, changes in normal function and medicines or supplements already taken. A short record often makes a consultation more useful.
Sensible next steps
A GP or cardiology assessment can confirm the rhythm with an ECG or longer monitoring. Do not self-start or stop blood thinners based on a smartwatch alert.
Medical assessment and where TCM fits
Medical management may address heart rate, rhythm and stroke prevention. The right plan depends on age, other conditions and bleeding/stroke risk.
TCM may support sleep, stress or general wellbeing in a medically stable person, but it does not substitute for ECG diagnosis or evidence-based stroke prevention.
TCM and conventional care can sometimes complement each other, but acute red flags, conditions needing imaging or blood tests, and diseases with established evidence-based treatment require diagnosis and safety to come first.
When not to wait
Palpitations with chest pain, fainting, severe breathlessness, new weakness, facial droop or speech difficulty needs urgent medical care.
