atrial fibrillation symptoms

Symptoms of Atrial Fibrillation 

Atrial Fibrillation reduces the heart’s efficiency and performance, which can make you feel generally unwell or experience other symptoms because the oxygen isn’t being properly delivered to all parts of your body.1,2

The symptoms can vary, but most commonly include one or more of the following: palpitations, fatigue, shortness of breath, general unwellness, dizziness, anxiety and chest pain.3,4,5

Silent Atrial Fibrillation 

It’s important to note that for some people AF may go unnoticed, in fact for around 15–30% of people they may experience no symptoms. This is commonly known as ‘silent AF’3,6 and these cases of AF need to be detected through a pulse check or through health screening.


How does catheter ablation work?

Causes of Atrial Fibrillation 

Atrial Fibrillation develops as a result of structural changes to the heart. The causes of AF are not always clear and can be complex.7,8,9 Possible causes are wide ranging with heart disease, age, family history, high blood pressure, alcohol consumption, obesity, and other chronic conditions all contributing risk factors to AF.7,10
