Inappropriate Pauses During Bradycardia Pacing in a Third‐Generation Implantable Cardioverter Defibrillator
Key result
In a patient with long QT syndrome, a third-generation ICD caused inappropriate pauses during bradycardia pacing due to automatic sensitivity increases, which was resolved by noninvasive reprogramming.

Population
A patient with long QT syndrome who received a third-generation implantable cardioverter defibrillator.
I
Intervention
Third-generation implantable cardioverter defibrillator (ICD) with bradycardia pacing

Outcome
Inappropriate pauses during bradycardia pacingsafety
Recognition of specific ICD sensing algorithms like 'lower threshold crossing' is crucial to identify and noninvasively correct inappropriate pacing pauses.

Cossú et al. (1997) conducted a case report in Long QT syndrome (n=1). Third-generation implantable cardioverter defibrillator was evaluated on Inappropriate pauses during bradycardia pacing. In a patient with long QT syndrome, a third-generation ICD caused inappropriate pauses during bradycardia pacing due to automatic sensitivity increases, which was resolved by noninvasive reprogramming.
