Analysis of the cardiac electrical signals in patients with Atrial Fibrillation

This study will be conducted retrospectively and prospectively to examine the 3D electro-anatomic maps and intracardiac signals of participants who have undergone AF ablation at the Lyell McEwin Hospital. A total of 400 electronic medical records will be accessed which includes both retrospective and prospective data. Electronic data will be collected to examine the 3D electro-anatomic maps and intracardiac signals of participants who have undergone AF ablation at the Lyell McEwin and Ashford Hospitals. A waiver of consent to collect retrospective data (5 years) for 200 patients is provided for this study (Central Adelaide Local Health Network Human Research Committee). Therefore, no patient contact or consent is required. Prospective data (n = 200) will be collected for five years from the start of the study (2024) until 2030 from participants who are booked for an AF ablation at the Lyell McEwin Hospital, Cardiology Department and Ashford Hospital. They will be informed about the study by one of the study investigators and required to provide Consent to collect data only. All participant data will be de-identified and given a unique study ID number.
