Why the study?
Does an AT/AF burden >= 5.5 hours detected by implantable devices increase thromboembolic and stroke risk?
Population
Patients with implantable device diagnostics measuring daily atrial tachyarrhythmia (AT/AF) burden
Comparison
AT/AF burden >= 5.5 hours on any of 30 prior days vs Patients with traditional AF with similar risk…

Supports device AT/AF burden monitoring for TE risk stratification; leaves open prospective trials on anticoagulation thresholds.
Does an AT/AF burden >= 5.5 hours detected by implantable devices increase thromboembolic and stroke risk?
Daily atrial tachyarrhythmia burden of 5.5 hours or more detected by implantable devices is associated with a doubled risk of thromboembolic events.
Glotzer et al. (2009) studied this question.
