AV hysteresis causing initiation of recurrent atrial arrhythmias

AV hysteresis causing initiation of recurrent atrial arrhythmias

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 wit...

Zusammenfassung: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.
