Honarbakhsh et al reported the BRUGADA-RISK score to identify a patient with Brugada Syndrome at greater risk for ventricular arrhythmia and/or sudden death. The authors are from multiple institutions in Europe.
Patient selection: Brugada syndrome without a history of cardiac arrest
Parameters:
(1) history of syncope that was probably arrhythmia-related
(2) spontaneous type 1 Brugada ECG pattern
(3) early repolarization in peripheral leads
(4) type 1 Brugada ECG pattern in peripheral leads

total score =
= SUM(points for all of the parameters)
Interpretation:
• minimum score: 0
• maximum score: 47
• The higher the score the greater the risk of ventricular arrhythmias or sudden death.
