Abstract 13486: Risk Stratification of Ventricular Fibrillation in Brugada Syndrome Using Non-invasive Scoring Methods

Aim: Risk stratification of ventricular fibrillation (VF) in Brugada syndrome remains controversial and it is difficult to describe using one parameter. We investigated whether we are able to assess VF risk using our non-invasive scoring method of each Brugada syndrome patients. Methods: We enrolled 46 patients with Brugada syndrome (45 men, average age 42 ± 3 years). Thirteen of the subjects had VF history or subsequent VF events (VF+) after implantable cardioverter defibrillator implantation. The frequency of Type1 Brugada ECG and positive TWA were significantly higher in VF+ patients than those without (Type 1 ECG 50% vs 4.8%, P=0.0003 and positive TWA 73.3% vs 6.7%, P Conclusions: The new scoring method using previous reported non-invasive risk factors of VF in Brugada syndrome is useful for assessing risk stratification in daily medical practice.
