Atriyal fibrilasyonan irregular rhythm worth taking seriously.
Atrial fibrillation (AF) is an irregular, often fast heartbeat that starts in the upper chambers of the heart. It is common, especially with age. It matters mainly because it raises the risk of stroke, and that risk can be greatly reduced.

Symptoms

- A fluttering, racing or irregular heartbeat
- Breathlessness, especially on exertion
- Tiredness and less energy for exercise

How it is diagnosed
The diagnosis starts with your history and an examination. These are the tests most often used to confirm it.
How it is managed
Stroke prevention
Your stroke risk is scored, and most people with AF are offered an anticoagulant (a blood thinner) to lower it.
Rate control
Medicines slow the heart so it pumps more efficiently, which often eases symptoms.
Rhythm control
Some people benefit from restoring a normal rhythm with medicine, cardioversion or ablation, arranged by referral.
Treating what drives it
Blood pressure, weight, alcohol, sleep apnoea and thyroid problems all affect how often AF comes back.

Common questions
Is atrial fibrillation dangerous?
It is rarely an immediate danger, but untreated it raises the risk of stroke and can weaken the heart over time. Both risks can be reduced with treatment.
Will I need a blood thinner for life?
It depends on your stroke risk score, which is based on your age and other conditions. The decision is reviewed as your circumstances change.
My smartwatch says I have AF. What should I do?
Keep the recording and book an appointment. A watch reading is a useful clue, and it is confirmed with a proper ECG.
