If you think you may have atrial fibrillation, also known as AF, here's everything you need to know. AF is a very common heart condition, which is essentially an irregular heart rhythm. It gets more common as we get older. And in the UK about 10% of patients over the age of 80, will have this heart rhythm abnormality.
However, we see patients from all age ranges. The number one most important thing with atrial fibrillation is getting the diagnosis, which can be done with a pulse check and ECG, and you may need other investigations in the hospital.
In terms of treatment, the single most important thing is reducing your risk of stroke. Having an irregular heart rhythm increases your risk of stroke, and the way we treat this is with blood thinners called anticoagulants. Nowadays, we may also use newer devices if you are not suitable to go onto blood thinners. What's important in AF? Well, we know now that lifestyle factors play a huge role in this.
So eating a healthy diet, exercising, looking after other conditions such as high blood pressure, diabetes, making sure you're not drinking too much alcohol, all these things play a really important role in AF. And by reducing your chances of developing AF, you are reducing your chances of other heart problems, such as heart failure and dementia. So it's really important to try and prevent this. If you have been diagnosed with AF, we can treat this nowadays with medications to control the heart rate or rhythm, and also newer minimally invasive procedures, which carry a very good success rate known as ablation. So, if you've been diagnosed with AF, don't worry. It's a very common condition.
There's lots we can do to help you and treat the success rate.

Is there a cure for atrial fibrillation?

Video Description
We can manage atrial fibrillation with medications, which help control the rhythm or reduce episodes. However, for a more long-term solution, we use procedures like ablation and radiofrequency ablation. These techniques have a high success rate, especially depending on the type of atrial fibrillation a patient has.

What does atrial fibrillation look like on an ECG?
0:43
Dr Syed Ahsan
Video Description
An ECG, or electrocardiogram, is a 12-lead test that records your heart's electrical activity from different angles. It provides insight into how your heart is functioning electrically. When your heart is in a normal rhythm, the ECG will show a regular pattern.
In atrial fibrillation, however, the rhythm is chaotic, and the spikes representing heartbeats appear at irregular intervals. This causes the ECG to look uneven. Additionally, we don’t see the typical P waves, which are signals from the top chambers of the heart (the atria) during normal rhythm. In atrial fibrillation, this absence of P waves further indicates the irregularity.

How does atrial fibrillation increase the risk of stroke?
0:31
Dr Syed Ahsan
Video Description
Dr Syed Ahsan explains that atrial fibrillation increases the risk of stroke because the irregular heartbeat allows blood to pool and clot in a sac near the heart. The clots can then travel to the brain and cause a stroke.

What is the difference between atrial flutter and atrial fibrillation?

Dr Syed Ahsan
Video Description
Dr Syed Ahsan, Consultant Cardiologist explains the differences between an atrial flutter and atrial fibrillation. Whereas an atrial flutter is a fast regular beating, atrial fibrillation is an irregular chaotic heart rhythm. Both conditions increase your risk of stroke and need to be taken seriously.

Dr Syed Ahsan
Video Description
There are many things that can increase your risk of atrial fibrillation (AF), including environmental factors, like smoking or drinking, or a family history. However, you can lower your risk. Dr. Syed Ahsan, a leading expert in heart rhythm disorders, advises maintaining a healthy weight, regular exercise, moderate alcohol intake, and a balanced diet to reduce your chances of developing AF. Addressing conditions like high blood pressure and sleep apnoea further lowers your risk of developing AF, so speak to us today.

If you have atrial fibrillation, it's important to understand your triggers and how to prevent episodes. In this video, Dr. Syed Ahsan describes some of the common triggers, including alcohol and stress, and who is more likely to trigger their AF. However, everyone's triggers are different, and you may have none at all. Visit our atrial fibrillation condition page to learn about the factors that increase your AF risk.
