Atrial fibrillation and stroke prevention
Atrial fibrillation (AF) is a common irregular heart rhythm. It can cause palpitations or breathlessness, or no symptoms at all. Because blood can pool in a small pouch of the heart called the left atrial appendage, AF increases the risk of stroke, so protecting against stroke is a central part of care.
1What you might notice
- A fast, irregular or fluttering heartbeat
- Breathlessness or reduced exercise capacity
- Tiredness or light-headedness
- Sometimes no symptoms; found on a pulse check or ECG
Sudden weakness of the face or arm, or slurred speech, may be a stroke. Call 000.
2Tests that help
- ECG
Confirms the rhythm.
- Holter monitor
Records the rhythm over 24 hours or longer when symptoms come and go.
- Echocardiogram
Looks at heart size, pumping and valves.
3Treatment options
- Blood thinners
Lower the risk of stroke for most people with AF.
- Rate and rhythm control
Medicines, and referral for procedures such as ablation where appropriate.
- Left atrial appendage occlusion
A small device that seals the appendage, for people who cannot safely take long-term blood thinners.
