MIMIC-IV-ECG: 800,000 Diagnostic 12-Lead Electrocardiograms

Approximately 800,000 diagnostic electrocardiograms from nearly 160,000 unique patients, matched to the MIMIC-IV Clinical Database. The ECGs are 10 seconds in length, sampled at 500 Hz, and use 12 leads. This subset is hosted on AWS Open Data and is provided by PhysioNet under the Open Database License.

Use Cases

• Train models for automated ECG interpretation based on 12-lead, 10-second waveforms.
• Develop methods for linking physiological waveforms to clinical reports based on available cardiologist report links.
• Conduct multimodal clinical research by linking ECG data to other patient information in the MIMIC-IV modules.

Strengths

• Approximately 800,000 diagnostic ECG records, providing a substantial volume for analysis.
• Waveforms are standardized: 12 leads, 10 seconds in length, and sampled at 500 Hz.
• Patients are matched to the MIMIC-IV Clinical Database, enabling linkage to broader clinical data.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
