The overall objective of this proposal is to evaluate the effect on quality of life of a comprehensive digital atrial fibrillation (AFib) management tool that will empower patients to a) take an active role in learning about AFib management options, starting and adhering to evidence-based therapies and lifestyle changes and b) to guide the patients during AFib episodes which are associated with anxiety and impairment in quality of life.

Researchers plan to evaluate the effectiveness of this novel digital toolkit in improving quality of life and decreasing AFib burden in a randomized clinical trial (RCT). A pilot study assessing feasibility and retention of the intervention was previously conducted (NCT05400837)
