MIMIC-III Waveform Database

Overview

The MIMIC-III Waveform Database contains thousands of recordings of multiple physiologic signals ('waveforms') and time series of vital signs ('numerics') collected from bedside patient monitors in adult and neonatal intensive care units (ICUs).

Data Collection

• 67,830 record sets for approximately 30,000 ICU patients, collected in a largely automated fashion from all bedside monitors in certain ICUs.
• Almost all record sets include a waveform record (typically ECG, ABP, respiration, PPG, and other signals digitized at 125 Hz) and a numerics record (periodic measurements such as heart rate, oxygen saturation, blood pressure sampled at 1 Hz or 1/min).
• Recording lengths vary; most are a few days in duration, but some are several weeks long.

Signals

• Waveforms: Up to 8 simultaneous channels including ECG (multiple leads), arterial blood pressure (ABP), photoplethysmogram (PPG), and respiration.
• Numerics: Heart rate, respiration rate, SpO₂, and systolic/mean/diastolic blood pressure, plus other vital signs as available.

Use Cases

• Developing and benchmarking patient monitoring algorithms for arrhythmia, hypotension, and respiratory distress.
• Training deep learning models for multi-signal physiologic event detection in critical care.
• Research on patient deterioration prediction and clinical decision support in ICUs.
