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.
