Atrial Fibrillation Burden: Moving Beyond Atrial Fibrillation as a Binary Entity

  • Risk factors and complications of atrial fibrillation (AF) are based on the presence or absence of AF, not the burden of AF.
  • AF burden is classified by type (paroxysmal or non-paroxysmal) and can be quantitatively defined by longest duration, number of episodes and proportion of time in the arrhythmia.
  • This scientific statement examines how to define and measure AF burden, burden related to CV and neurological outcomes, and effects of lifestyle and risk modification on AF burden.
