High Density Mapping in Brugada Syndrome

The current study has the following objectives: 1. To characterize the changes in amplitude and duration of epicardial right ventricular outflow tract electrograms captured through a multipolar mapping catheter in patients with Brugada syndrome before and after an ajmaline challenge. 2. To investigate the relationship between the above cited invasive electrophysiological findings and non invasive ECG imaging (ECGI) of the epicardial layer of the right ventricular outflow tract (RVOT) of patients affected by Brugada syndrome and undergoing substrate thoracoscopic catheter ablation.
