What is atrial fibrillation?
The NHS describes symptoms of AF as an irregular pulse, palpitations, a heart rate over 100 beats a minute, tiredness, chest tightness, breathlessness, and feeling light-headed or dizzy.
Some people have no symptoms at all, and AF is found during a routine check-up or tests for another problem.
AF raises the risk of blood clots and stroke. Anticoagulant (blood-thinning) medicines can lower this risk.
What an AF assessment covers
- Confirming the diagnosis
- Looking for related conditions, such as high blood pressure, an overactive thyroid or sleep apnoea
- Assessing your stroke risk and whether anticoagulant medicine is right for you
- Planning treatment with medicines to control your heart rate and rhythm
- Ongoing follow-up and medication review
