Why the study?
AV Search+ combined with sensor rate pacing can cause short-coupled atrial paced intervals that may be proarrhythmic, leading to recurrent atrial arrhythmias.
Do device programming changes reduce automatic mode switch burden in a patient with AV hysteresis-induced atrial arrhythmias?

Do device programming changes reduce automatic mode switch burden in a patient with AV hysteresis-induced atrial arrhythmias?
AV Search+ combined with sensor rate pacing can cause short-coupled atrial paced intervals leading to proarrhythmic events, which can be resolved with appropriate programming changes.
A 73-year-old male with dual-chamber implantable cardioverter defibrillator (Teligen, Boston Scientific, Marlborough, MA, USA) had multiple episodes of automatic mode switch (AMS) during clinical follow-up. Over 50% of these demonstrated a similar pattern of initiation. AV Search+ in combination with sensor rate pacing can cause short-coupled atrial paced intervals that can be proarrhythmic. After programming changes were made AMS burden has significantly decreased.
