Inappropriate Discharges of an Implantable Cardioverter Defibrillator Secondary to Automatic Adjustable Gain of Atrial Tachycardia
Key result
Automatic adjustable gain in an implantable cardioverter defibrillator caused inappropriate discharges by falsely sensing atrial tachycardia as ventricular fibrillation after His bundle ablation.

Intervention
Third generation implantable cardioverter defibrillator with automatic adjustable gain settings

Outcome
Inappropriate ICD discharges / satisfaction of ventricular fibrillation detection criteriasafety
Automatic adjustable gain settings in third-generation ICDs can lead to inappropriate shocks by sensing atrial tachycardia in patients with prior His bundle ablation.
