Medicines for Atrial flutter
An abnormal heart rhythm in which the upper chambers beat very fast in a regular pattern — related to atrial fibrillation, and managed to control the rhythm and prevent stroke.

Quick answer
What is Atrial flutter?
Atrial flutter is a type of abnormal heart rhythm (arrhythmia) in which the upper chambers of the heart (the atria) beat very rapidly in an organised, regular pattern, often making the heart beat fast. It is closely related to atrial fibrillation and the two can occur in the same person.
- How it is treated: Treatment has three aims: controlling the heart rate or restoring normal rhythm, reducing the risk of stroke, and treating any underlying cause.
- Self-care: Managing conditions that contribute (such as high blood pressure and thyroid problems), limiting alcohol and caffeine if they trigger symptoms, staying active, and taking prescribed treatment (including anticoagulation) all help.
- When to seek help: See a GP about palpitations, breathlessness or dizziness.
What it is
Atrial flutter is a type of abnormal heart rhythm (arrhythmia) in which the upper chambers of the heart (the atria) beat very rapidly in an organised, regular pattern, often making the heart beat fast. It is closely related to atrial fibrillation and the two can occur in the same person. Symptoms can include palpitations (a fast or fluttering heartbeat), breathlessness, tiredness, dizziness and chest discomfort, though some people have few symptoms. Like atrial fibrillation, atrial flutter increases the risk of blood clots forming in the heart, which can cause a stroke, so assessing and reducing this risk is a key part of care. It is diagnosed with an ECG (heart tracing).
How it is treated
Treatment has three aims: controlling the heart rate or restoring normal rhythm, reducing the risk of stroke, and treating any underlying cause. The rhythm can often be controlled with medicines or, very effectively, with a procedure called catheter ablation, which targets the small area of heart tissue driving the flutter and can cure many cases. An electrical shock treatment (cardioversion) can restore normal rhythm in some situations. Crucially, the stroke risk is assessed, and anticoagulation ("blood thinning") is often recommended to prevent clots, as in atrial fibrillation. Any contributing conditions, such as high blood pressure or thyroid problems, are also managed. Care is guided by a cardiology team.

Beyond medication
Lifestyle and self-care
Managing conditions that contribute (such as high blood pressure and thyroid problems), limiting alcohol and caffeine if they trigger symptoms, staying active, and taking prescribed treatment (including anticoagulation) all help. Report any stroke symptoms immediately.
When to get help
When to see a doctor
See a GP about palpitations, breathlessness or dizziness. Call 999 for stroke symptoms (FAST), severe chest pain, or fainting, or if a very fast heartbeat comes with severe breathlessness or feeling faint.
Not sure how urgent it is? It is always OK to call NHS 111 for advice, day or night.
Answers
Atrial flutter: frequently asked questions
How is atrial flutter different from atrial fibrillation?
In atrial flutter the upper chambers beat very fast but in a regular, organised pattern, whereas in atrial fibrillation they beat irregularly. Both are related, can occur together, and both raise the risk of stroke.
Can atrial flutter be cured?
Often, yes — a procedure called catheter ablation targets the tissue driving the flutter and can cure many cases. Stroke-prevention treatment and managing underlying causes remain important.
