Lobachevsky University Electrocardiography Database (LUDB) is ECG signal database for validation of ECG delineation algorithms. The database consists of 200 10-second 12-lead ECG signal records representing a wide class of different morphologies of the ECG signal.
The boundaries of the ECG signal complexes were manually annotated by cardiologists for all 200 records independently for each lead. In addition, all records have a complex diagnosis.
You can use LUDB for academic purposes. Please cite
