If your heart rhythm feels irregular, you may have atrial fibrillation. We recently spoke to Dr Saagar Mahida, a leading cardiologist and electrophysiologist, to learn more about the symptoms, treatment and factors that should be considered when treating this condition.
 


What is atrial fibrillation?

The normal heart rhythm, referred to as sinus rhythm, is a regular rhythm with the heart rate being regulated by the level of physical activity or stress. In patients with atrial fibrillation, this organised heart rhythm is replaced by a chaotic, irregular and often rapid heart rhythm. In the absence of treatment, the heart rate is commonly disproportionately high for the level of activity in patients with atrial fibrillation.


What are symptoms of atrial fibrillation?

The fast and irregular heart rhythm in patients with atrial fibrillation may cause palpitations (an uncomfortable sensation of a fast irregular heart beat). Furthermore, because the heart does not pump blood in an effective way, atrial fibrillation may cause a reduction in exercise capacity, difficulty in breathing when exercising, and fatigue. These symptoms can be debilitating and have a significant impact on quality of life.
 

In patients with atrial fibrillation, the rhythm abnormality may be continuous (persistent atrial fibrillation) or may be intermittent, with transient episodes occurring with a recurrent pattern (paroxysmal atrial fibrillation). These episodes may last anywhere from a few seconds to a number of hours.

 

What are the treatment options for atrial fibrillation?

Treatment of atrial fibrillation focuses on two main areas. The first is prevention of stroke with anticoagulant (blood thinning) medications, and the second is eliminating symptoms and improving quality of life. Available options for treating symptoms of atrial fibrillation include performing a procedure to cure the heart rhythm abnormality, referred to as a catheter ablation procedure, or treatment with medications. In certain circumstances, a combination of the two may be necessary to treat atrial fibrillation.


Deciding on the best treatment strategy for atrial fibrillation

There are a number of important considerations when deciding between a catheter ablation procedure or medications to treat atrial fibrillation. For patients with paroxysmal (intermittent) atrial fibrillation, in the majority of cases, patient choice is at the centre of the decision. The decision to have a catheter ablation procedure may be influenced by the fact that regular medications do not fit with a patient’s lifestyle, the patient experiences unpleasant side effects associated with medications, or medications are not effective. The role of catheter ablation as a first-line treatment has expanded progressively in recent years.
 

Amongst patients with atrial fibrillation that is present all the time (persistent atrial fibrillation), the decision to undertake a catheter ablation procedure may involve additional considerations (in addition to patient choice). The decision commonly involves consideration of the amount of time the heart has been in continuous atrial fibrillation, and potentially the findings of a heart scan (echocardiogram or cardiac MRI scan). Overall, the physician will take multiple factors into account, including the patient’s own preferences and the overall clinical picture, before coming to a decision.
