Actual (reported)The aim of this research is to classify patients by the dominant mechanism of continuous atrial electrical activation during atrial fibrillation. This approach seeks to improve on existing classifications which are based solely on the duration of the arrhythmia (\<7 days, \>7 days and \>1 year). This is a cohort study. Patients undergoing clinically indicated electrophysiology study or AF ablation will have invasive assessment of cardiac electrophysiological profile at the time of their planned procedure, undergo 2-week ambulatory monitoring before and after the procedure, complete symptom questionnaires before and after their procedure and undergo atrial cardiac magnetic resonance imaging before their procedure.

Actual (reported)Proportion of patients with each mechanism of atrial fibrillation defined by computational modelling
The primary outcome is the creation of patient specific computational models for the investigation of atrial fibrillation mechanisms in patients. Mechanisms of atrial fibrillation will be defined based on computational modelling results and each patient will be assigned to the dominant mechanism of atrial fibrillation present.
4 years
Atrial properties - atrial structural and functional properties will be compared between patients in each mechanistic atrial fibrillation group (as defined in Outcome 1)
4 years
Treatment effects - burden of atrial fibrillation in patients classified as 'successfully treated' compared to those classified as 'not successfully treated' using the modelling framework (as defined in Outcome 1)
4 years
Up to 115 patients undergoing radiofrequency catheter ablation will be enrolled.
To include assessment of atrial size, shape, function, fibrosis and fat
To include assessment of atrial voltage and local activation time
Up to 115 patients undergoing electrophysiological assessment will be recruited with inclusion and exclusion criteria as indicated above.
