Recommendations

As issued by the authors

  1. Atrial fibrillation (AF) burden is defined as the proportion of time spent in AF expressed as a percentage of the recording time, undertaken during a specified monitoring duration.

  2. A continuous or near-continuous monitoring duration is required for valid, comparable AF burden assessment and must be reported with the AF burden.

  3. The unified definition applies independent of comorbidities and outcomes; disease-specific actionable thresholds need to be defined according to targeted clinical outcomes in specific populations.

  4. The duration of the longest episode of uninterrupted AF, expressed as a time duration, should also be reported when appropriate.
