In a Brugada patient, inappropriate ICD shocks due to atrial fibrillation occurred 34 years after last VF-related syncope, indicating arrhythmia risk may shift with age.
Does arrhythmia risk shift from VF to AF with age in Brugada syndrome?
This case highlights the risk of incident atrial fibrillation causing inappropriate shocks in aging Brugada syndrome patients with single-lead ICDs, and demonstrates the efficacy of pulmonary vein isolation in this setting.

Atrial fibrillation (AF) is a significant cause of inappropriate implantable cardioverter defibrillator (ICD) shocks. A male patient in his 70s was diagnosed with Brugada syndrome (BrS) in his 40s following ventricular fibrillation-induced syncope. He had implanted a single-lead ICD in his 50s. 34 years after the last syncope, the ICD delivered four inappropriate shocks due to paroxysmal AF, successfully treated with pulmonary vein isolation. Ageing likely increased AF burden, despite its infrequency during follow-up. This case highlights the limitations of single-lead ICDs in AF detection and the importance of tailored management in elderly BrS patients.
