Feasibility of Improving Risk Stratification in Brugada Syndrome

Feasibility of Improving Risk Stratification in Brugada Syndrome (BrS), retrospective cohort study To study the reproducibility and specificity of V-CoS for activation heterogeneities predisposing to VT/VF in a larger series of BrS patients and determining the incidence of low V-CoS score in a larger cohort of control patients. Population of 10 patients undergoing ablation for non-VT arrhythmia, 10 patients with atrial fibrillation, 10 relatives of BrS sufferers, who have confirmation of no pathology,10 patients with previous out-of-hospital cardiac arrest due to ischaemia, but with full revascularisation and recovery of left ventricular function, 10 elite athletes, 50 BrS sufferers with previous sudden cardiac death or appropriate Implantable cardioverter-defibrillator (ICD) therapy for VT/VF.
