Abstract
In a 64-year-old male patient with an implantable cardioverter defibrillator (ICD) for secondary prevention of sudden cardiac death, a shock occurred some months after generator exchange and downgrade to a single-chamber system. Careful analysis of the stored electrogram revealed a rare cause that could be confirmed at the time of operative revision.
Zusammenfassung
Bei einem 64-jährigen Patienten mit einem implantierbaren Kardioverter-Defibrillator (ICD) zur Sekundärprophylaxe des plötzlichen Herztods kam es einige Monate nach Generatorwechsel und Downgrade auf ein Ein-Kammer-System zu einer Schockabgabe. Die sorgfältige Analyse des gespeicherten Elektrogramms ergab eine seltene Ursache, die sich zum Zeitpunkt einer operativen Revision bestätigte.
