STROKE, ATRIAL FIBRILLATION, PATHOPHYSIOLOGY
The original intervention was designed by J.G.K. and A.T. The development process is described elsewhere.The final intervention was a series of 4 videos: (1) “What is AF?” discussing cardiac anatomy, the ECG, and AF risk factors; (2) “Management of Atrial Fibrillation,” addressing the pathophysiology of AF, including the association with stroke risk and pharmacological and procedural management options; (3) “Lifestyle advice,” specifically addressing lifestyle modifications proven to reduce AF burden; and (4) “AF summary,” summarizing previous videos. Patients randomized to the intervention group were automatically directed to watch all 4 videos in order immediately after baseline data collection. The database recorded when videos were opened by participants, facilitating calculation of the number of videos watched. After their clinic appointment, intervention participants were emailed links to review the video series weekly. Ongoing engagement with the intervention was determined by participants and not a requirement of study participation. Videos are freely available elsewhere.
