This is an extract from the guidance. The complete guidance is available at


Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia and if left untreated is a significant risk factor for stroke and other morbidities. This guideline contains evidence-based guidance on the diagnosis and management of AF as it occurs in emergency, primary, post-operative and secondary care. It also gives recommendations for referral to specialist services.

The recommendations in this guideline were graded according to the quality of the evidence they were based on. The gradings are available in the full guideline and are not shown in this web version.
