Activating atrial overdrive pacing compromises AHRE specificity for true AT/AF; clinicians should interpret device episodes cautiously and researchers should reassess algorithm utility.
Does an atrial overdrive pacing algorithm affect the specificity of atrial tachyarrhythmia detection by AHRE in patients with dual chamber pacemakers?
The use of an atrial overdrive pacing algorithm in dual chamber pacemakers significantly reduces the specificity of atrial high rate episodes for detecting true atrial tachyarrhythmias due to the induction of repetitive non-reentrant ventriculoatrial synchrony.
