BACKGROUND: The objective of this study was to determine the prevalence of electrocardiographic (ECG) findings suggestive of @entity1164 risk in apparently healthy young Korean @entity1 . METHODS: We administered questionnaires that elicited personal and family histories and performed ECGs on 10,867 male subjects (mean age, 20.9 years). The subjects with abnormal ECG findings underwent echocardiography, a treadmill test, Holter monitoring, a @entity6237 provocation test, or an electrophysiologic study (EPS) according to the ECG findings and histories. RESULTS: Of the subjects, 5.95% had left @entity123 on ECG, but no subjects had @entity1121 by echocardiography. The percentage of subjects with a Brugada ECG pattern was 0.90%. We identified one subject with a positive result on the @entity6237 provocation test. The percentage of subjects with a preexcitation ECG was 0.17%. In two of the subjects, @entity4710 was induced in the EPS. Of the subjects, 0.05% had epsilon waves, but there were no subjects with @entity4128 right @entity67 / @entity296 by echocardiography. The percentage of subjects with long QT intervals was 0.02%, but there were no @entity943 on the treadmill test or Holter monitoring. CONCLUSIONS: The prevalence of a Brugada ECG pattern in apparently healthy young @entity1 is higher in Korea than other countries.
