Inappropriate ICD shock occurred 34 years after the last syncope in a symptomatic Brugada patient: does arrhythmia risk shift from VF to AF with age in Brugada syndrome?

Key Result

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.

Key Points

• To assess the shift in arrhythmia risk from ventricular fibrillation to atrial fibrillation with age in Brugada syndrome.
• Case study of a male Brugada syndrome patient diagnosed in his 40s.
• Patient history included ventricular fibrillation-induced syncope and ICD implantation.
• Tracking of arrhythmias and ICD shocks over a long-term follow-up period.
• Patient received four inappropriate ICD shocks due to paroxysmal atrial fibrillation.
• Pulmonary vein isolation successfully managed the arrhythmia.
• Age-related increase in atrial fibrillation burden noted despite infrequent occurrences during follow-up.
