Abstract
A thesaurus (logically ordered list) of statements for the ECG annotation has been developed. 549 ECGs from the PTB Diagnostic ECG Database were independently annotated by 3 clinicians using this thesaurus and web interface. The resulting independent annotations did not match (the proportion of matches was from 3 to 100% for different groups of conclusions in pairwise comparison of annotators). The annotations were agreed, for which a special procedure was developed. The procedure includes participation of moderators (highly qualified physicians) and using videoconferencing. Annotations are published in the public domain and can be used both for the purposes of knowledge control and for testing the accuracy of the automatic ECG analysis algorithms and software.
