Atrial Fibrillation

An irregular pulse could be a sign that you have an abnormal heart rhythm. Atrial Fibrillation (AF) is one of the most common forms of an abnormal heart rhythm and a major cause of stroke.

That's why it's important to find out if you have it, because you can get effective treatment to reduce the risk of stroke.

Normally, your heart’s natural pacemaker sends out regular electrical impulses. AF happens when those impulses fire off from different places in the atria (the top chambers of the heart) in a disorganised way.

People with AF have an irregular and sometimes fast pulse. You can check to see if you might have AF simply by feeling your pulse.

Around 800,000 people in the UK have AF - roughly one in 100 - and mostly aged 55 and over.

What causes AF?

Causes include high blood pressure, heart valve disease, thyrotoxicosis (overactive thyroid gland) and excess alcohol consumption.

It’s also associated with coronary heart disease. But in many patients no underlying cause can be found. Sometimes the AF can be resolved once the underlying condition has been dealt with.

What are the symptoms of AF?

Symptoms can include palpitation (being aware of your heart beat), tiredness, shortness of breath, dizziness or feeling faint. However, some people only have mild symptoms, while other people have no symptoms at all.

How can AF be detected?

AF can be detected by feeling the pulse at your wrist. The pulse will feel irregular and beats may be variable in strength.

Some people don’t realise they have AF. It’s only discovered when they have a pulse check or ECG (a test which records the electrical activity of the heart).

If your pulse is irregular or if you’re concerned in any way about your pulse you should make an appointment to see your GP.

Is an irregular pulse always due to AF?

Occasional irregularities such as missed beats or extra beats are very common and usually nothing to worry about.

AF on the other hand is continuously irregular with no pattern to it at all.

What are the complications of AF?

It can increase the risk of a blood clot forming inside the chambers of the heart, which can lead to a stroke. AF increases stroke risk by around four to five times.

Although AF can greatly increase the risk of stroke, there are other factors that can contribute to a stroke. These include smoking, high cholesterol, high blood pressure,physical inactivity, being overweight and diabetes.

With appropriate treatment the risk of stroke, can be substantially reduced. An anticoagulant (blood thinner) drug called Warfarin is the most effective treatment to reduce the risk of stroke in people with AF.

What should you do if your pulse is irregular?

If your pulse is irregular or if you’re concerned in any way about your pulse you should make an appointment to see your GP.
