Irregular Heartbeat & Atrial Fibrillation
An irregular heartbeat — most often atrial fibrillation (AF) — is common and treatable. Here's what it is, why it matters, and how a consultant cardiologist can diagnose it and plan your care.

An irregular heartbeat means your heart is not beating in its usual steady rhythm. The most common type is atrial fibrillation (AF), where the upper chambers of the heart beat irregularly and often fast.
Some people notice palpitations, breathlessness or tiredness; others have no symptoms and it is picked up on a routine check. AF matters because it raises the risk of stroke — and that risk can be reduced with the right treatment. If an irregular heartbeat comes with chest pain, fainting or severe breathlessness, call 999 — do not wait for a private appointment.
Symptoms of irregular heartbeat & atrial fibrillation.
Some people with AF feel nothing at all. With chest pain, fainting or severe breathlessness, call 999.
Why it happens.
AF becomes more common with age and is linked with other conditions that put strain on the heart. Sometimes no clear cause is found.
Don't wait for it to settle.
Early assessment helps you get the right treatment sooner. See a specialist if:


Confirming the rhythm — and your stroke risk.
Dr Khalid Khan starts with a full consultation and examination. An irregular heartbeat is confirmed on an ECG (heart trace); because it can come and go, ambulatory monitoring may be arranged to capture it, and an echocardiogram (ultrasound of the heart) to look at the heart's structure. These tests are arranged as part of your care, and the fee for each is confirmed at your consultation before you go ahead.
What an ECG involves →How irregular heartbeat & atrial fibrillation is treated.
Treatment depends on the type and cause — it usually aims to control the heart rate or rhythm and to reduce the risk of stroke.
