MIMIC-IV-ECG-Ext-ICD: Diagnostic labels for MIMIC-IV-ECG

The number of publicly available ECG datasets has increased tremendously in
the past few years and several of these datasets have developed into widely
used benchmarking datasets. However, most of them exhibit a common limitation,
namely the reliance on retrospective annotation and a lack of clinical ground
truth. This represents a serious limitation compared to closed in-hospital
datasets. To circumvent this issue, we propose the MIMIC-IV-ECG-Ext-ICD
dataset by linking the samples from the MIMIC-IV-ECG dataset to clinical
ground truth from the MIMIC-IV dataset, in the form of ED and hospital
discharge diagnoses. We release this derived dataset to foster further
research on ECG-based prediction models with clinical ground truth and build a
resource for benchmarking clinical ECG prediction models.
