NCT00173342

Brief Summary

This study is to determine 1) the incidence of altered right bundle conduction, including CRBBB, IRBBB or rsR' pattern in the Taipei city based on the school survey databank from 1999 to 2002, 2) the associated cardiac lesions, 3) clinical presentations relevant to the altered right bundle conduction, 4) the association with QTc prolongation and dispersion and HRV from a 5-minutes recording. Finally, molecular characterization for those with CRBBB or Brugada pattern EKG, especially those with positive family history will be studied.
