12-lead or 15-lead is to evaluate the performance of the automatic ECG analyzer. In addition to
the normal data, the database also includes clinically confirmed ECGs of variety cases, such as
left ventricular hypertrophy, right ventricular hypertrophy, every part of myocardial infarction
and ventricular hypertrophy accompanying myocardial infarction. The database has made a great
contribution to the study of electrocardiology, which is, the CSE group published a report on the
recommended standard for general ECG measurements based on the investigation and study of
the database, which has been widely recognized by the world.
