Description of intervention(s) / exposure
The study population will consist of participants with paroxysmal and non-paroxsmal atrial fibrillation (AF) or atrial flutter (AFI) with a diagnosis of non-valvular clinical atrial fibrillation (NVAF). Definition of clinical NVAF is based on 2018 Australian Clinical Guidelines for the Diagnosis and Management of Atrial Fibrillation, which by accepted convention, a documented episode lasting at least 30 seconds is diagnostic.
Clinical investigation data for patients with AF will be collected at baseline and every 12 month, for a minimum of 5 years. Participants will attend an 1-hour consultation at the study hospital every 12 months. Other clinical data will be collected from their medical record in an ongoing basis.

Statistical methods / analysis
For the primary objective as we are describing outcomes of participants we will use means and standard deviation for continuous normally distributed data and medians and interquartile range (IQR) for skewed data and frequencies and percentages for categorical variables.

For secondary objectives, association between management of paroxysmal and non-paroxysmal AF and clinical outcomes will be investigated using regression models appropriate for outcomes (e.g. linear regression for continuous normally distributed outcomes) with adjustment for confounding. This model will be repeated for association between treatment strategies and AF control.
