Large Scale Arrhythmia Database (LSAD)
Overview
The large scale arrhythmia database (LSAD) is a large-scale, multi-center, multi-lead, and multi-class ECG dataset for arrhythmia detection. The dataset contains ECG recordings from 45,152 patients. The dataset is collected from 3 different centers: Shaoxing People's Hospital, the Second Affiliated Hospital of Zhejiang University, and the First Affiliated Hospital of Zhejiang University. The dataset contains 11 different arrhythmia classes and 1 normal class. The dataset is collected from 12-lead ECGs and is annotated by a team of expert cardiologists. The dataset includes over 100 scp codes.
