Atrial fibrillation burden is underestimated by non-invasive monitoring: the CIRCA-DOSE trial

View Full Paper
MAMartín AguilarLMLaurent MacleGDGeoffroy Ditac

Key Points

  • Non-invasive monitoring significantly underestimates the burden of atrial fibrillation, impacting treatment strategies.
  • CIRCA-DOSE trial revealed discrepancies in monitoring with findings suggesting persistent atrial fibrillation in many patients.
  • Assessment using rigorous monitoring tools identified greater atrial fibrillation burden than previously reported.
  • The trial highlights a need for more accurate monitoring of atrial fibrillation to improve patient outcomes.
