Some Clinical Advances on Brugada Syndrome

Abstract: Brugada syndrome is an inherited arrhythmogenic disorder that exhibits ECG ST-segment elevation with a negetive T-wave in the right precordial leads (V1-V2), with normal heart structure, predisposing to VF and SCD. Its symptoms include syncope, nocturnal agonal respiration and cardiac arrest. Recently, reserches on Brugada syndrome had archived some advances, for examples, regarding to exposuring concealed Brugada 1 type ECG, besides pharmacological provocation, there are two orter methods: putting right precordial lead on the second intercostal space or Holter monitoring; early repolarization(J-wave) has important value in prognostic judgment of Brugada syndrome; radiofrequency catheter ablation was generally applied only in epicardium of RVOT in the past, while it has been applied in endocardium of RVOT today. Therefore, the endocardium of RVOT can be considered as an alternative site in the treatment of recurrent VF in Brugada syndrome
