Zusammenfassung

Das Brugada-Syndrom zählt zu den Ionenkanalerkrankungen. Elektrokardiographisch finden sich transiente oder persistierende bogenförmige ST-Streckenhebungen in mindestens einer rechtspräkordialen EKG-Ableitung. Die Klinik der Patienten ist durch Kammertachykardien, einen plötzlichen Herztod oder Synkopen charakterisiert, wobei aber die Mehrzahl der Betroffenen wahrscheinlich zeitlebens asymptomatisch bleibt. Die richtige EKG-Diagnose ist eine besondere klinische Herausforderung. Der implantierbare Kardioverter-Defibrillator (ICD) ist der einzige etablierte Schutz vor einem plötzlichen Herztod. Insbesondere in der Primärprophylaxe ist eine individuelle Risikostratifikation von großer Bedeutung. Das Ziel dieses Artikels ist es, einen Überblick über den aktuellen Stand der Risikostratifikation und der therapeutischen Möglichkeiten beim Brugada-Syndrom zu geben.

Abstract

Brugada syndrome is ion channelopathy defined by coved type ST-elevation in at least one right precordial ECG lead. Patients may suffer from ventricular tachycardia/fibrillation, which may cause syncope or sudden cardiac death. The majority of patients are likely to remain asymptomatic throughout life. A correct ECG diagnosis remains challenging. The implantable cardioverter/defibrillator (ICD) is the only established therapy to protect against sudden cardiac death. Thus, individual risk stratification is of major clinical relevance in primary prevention. The present article gives an update on current risk stratification and novel therapeutic options apart from ICD therapy.
