Independent, single center, prospective study, to evaluate the efficacy, in consecutive BrS patients undergoing catheter ablation, at medium-long term follow-up after epicardial substrate homogenization. The target area is defined collecting signals using high density and high resolution mapping with equi-spaced electrode array. The ablation of abnormal fragmented prolonged low-frequency ventricular electrograms is performed by contact force catheter.
