Key result
Brugada syndrome prevalence in idiopathic ventricular fibrillation patients ranged from 3% to 24% depending on criteria, with similar recurrence rates between Brugada and non-Brugada patients (P=ns).
Why the study?
What is the prevalence of Brugada syndrome and the long-term recurrence rate of ventricular tachyarrhythmias in patients with idiopathic ventricular fibrillation?
Observational (n=37)
No
What is the prevalence of Brugada syndrome and the long-term recurrence rate of ventricular tachyarrhythmias in patients with idiopathic ventricular fibrillation?
Absolute Event Rate: 33% vs 46%
p-value: p=ns
The prevalence of Brugada syndrome in idiopathic VF patients varies widely based on diagnostic criteria, but all such patients face a substantial long-term risk of recurrent ventricular tachyarrhythmias.
No takes yet. Share an insight, caveat, or question.
Idiopathic VF warrants close monitoring regardless of Brugada features; leaves open standardized criteria for phenotyping and risk stratification.
Carol Ann Remme (2001) conducted an observational in Idiopathic ventricular fibrillation (n=37). Brugada syndrome diagnostic criteria vs. Patients without Brugada syndrome was evaluated on Recurrent episode of syncope, ventricular tachyarrhythmias or sudden death (p=ns). Brugada syndrome prevalence in idiopathic ventricular fibrillation patients ranged from 3% to 24% depending on criteria, with similar recurrence rates between Brugada and non-Brugada patients (P=ns).
