Early Response after Catheter Ablation of the Epicardial Substrate in a Patient with Brugada Syndrome Can Be Predicted by High Precordial Leads

Figure 3

ECGs of the Brugada syndrome patient showing recordings of the anterior precordial leads: V1-2 leads from the 4th intercostal space and high precordial leads (V5 and V6 positioned cranially from V1 and V2) from the 3rd intercostal space. (a) Baseline before catheter ablation; (b) three days after ablation; (c) one month after ablation. Note the disappearance of the Brugada pattern at high precordial leads (V5-6) in the early stage and then at standard precordial V1-2 leads after catheter ablation. (d) The flecainide provocative test after three months of ablation revealed unmasking of type I Brugada pattern. ECG = electrocardiogram.
