The aim of treatment for AF is to prevent complications, particularly stroke, and alleviate symptoms. Treatments include anticoagulants to reduce the risk of stroke and treatments designed to restore or maintain a normal heart rhythm or slow the heart rate in people who remain in atrial fibrillation.
Non-pharmacological treatments include electrical cardioversion, which may be used to ‘shock’ the heart back to its normal rhythm and catheter ablation which is the procedure used to try to cure atrial fibrillation.
Below are a few of the methods used for managing Atrial Fibrillation:
Anticoagulants are medicines that help prevent blood clots. They’re given to people at a high risk of getting clots, to reduce their chances of developing serious conditions such as strokes or blood clots in a major artery when AF is present.
Beta-blockers, also known as beta-adrenergic blocking agents, are medications that lower heart rate and help to try to prevent episodes of AF. They also reduce your blood pressure, are used to treat angina and a number of other conditions.
Ablation is a technique of heating or freezing small areas of tissue within the heart to destroy that tissue to prevent abnormal heart rhythms from occurring. It is the only method of curing AF and is offered to patients with symptoms which cannot be controlled with medications or if the AF causes impairment of heart function. Ablation for AF is now by far the most commonly performed ablation procedure in the world.
Digoxin is used to slow the heart rate in patients with atrial fibrillation.
Electrical Cardioversion is a procedure in which an electric current is used to reset the heart’s rhythm back to its normal pattern (normal sinus rhythm). The electric current is applied through adhesive patches applied to the chest wall. It is only ever temporary but can still be useful to quickly restore normal rhythm when drugs have failed or are inappropriate.
These management options are not exhaustive and you should speak with an atrial fibrillation specialist to discuss the course of treatment that is right for you. Click the links below to find out more about atrial fibrillation or to book an appointment with Dr Segal.
