Intervention
EVENT
All participants will undergo non-invasive ECG monitoring (The Zenicor database has an algorithm that classifies and tags each ECG trace as ‘no tag’, ‘possible AF’ or ‘poor quality’. The algorithm has been tested in 80 149 ECGs and the negative predictive value for ECGs classified as normal is 99.9%.Once ECG monitoring reports have been reviewed, a standardised results letter will be sent to the participant and the general practitioner (GP). Results letters will be sent for all participants, irrespective of whether AF is diagnosed or not. The management of AF will be at the discretion of the GP, allowing doctor and participant to discuss the management strategy, including anticoagulation, independently and in line with how new cases of AF diagnosed in the community are managed in routine clinical practice. A diagnosis of AF does not require immediate action, but if there is a finding meeting the criteria for an emergent event per current clinical practice standards according to the National Institute for Health and Care Excellence, participants and appropriate clinicians will be notified. Actions will be taken following the same procedures as the established clinical workflow.
