Datasets
This page provides details of publicly available datasets that may be useful for research into biomedical signal processing techniques.
Photoplethysmogram (PPG) Datasets
| Dataset | Signals | Overview of protocol |
|---|---|---|
| CapnoBase | PPG, ECG, resp | Signals from patients during elective surgery and routine anaesthesia. (ref: 1 ). |
| MESA Polysomnography | PPG, ECG, EEG, resp, others | Recordings from overnight polysomnography (sleep) studies. (ref: 1 2 ). |
| MIMIC | PPG, ECG, resp, BP, others | Recordings during critical care admissions |
| PPG-DaLiA | PPG, ECG, resp, accel, EDA | Recordings during activities of daily living |
| PPG Diary 1 | Dual wavelength PPG | PPG signal measured at the thumb from a single participant for 28 days. The participant recorded their activities of daily living, and any technical problems (ref 1). |
| Pulse Wave Database | PPG, BP, blood flow, blood vel | Simulated arterial pulse waves at a range of common measurement sites for 4,374 virtual subjects aged 25-75 years, representative of healthy adults (ref 1) |
| Vortal | PPG, ECG, resp | signals acquired from young and elderly healthy subjects at rest (ref: 1 2 ). |
| WESAD | PPG, ECG, resp, accel, others | Recordings at baseline and during amusement, stress and meditation |
Electrocardiography (ECG) Datasets
| Dataset | Signals | Overview of protocol |
|---|---|---|
| Physionet CinC 2017 Challenge Dataset | ECG | Handheld, single-lead recordings alongside heart rhythm labels. |
The Physionet CinC 2017 Challenge Dataset contains data recorded from handheld ECG devices, alongside reference labels of the rhythm for each recording. This Matlab Script collates the data into a single Matlab file for analysis. The file contains 30-second ECG recordings, alongside reference labels of the heart rhythm.
Fetal ECG Datasets
Table 1 in this article provides a list of fetal ECG datasets.
Other Datasets
| Dataset | Signals | Overview of protocol |
|---|---|---|
| Virtual Database of Pulse Waves | BP, blood flow, blood vel | Pulse waves simulated at several arterial sites under a range of cardiovascular conditions (refs: 1 and 2). Simulated using the Nektar1D model of pulse wave propagation (ref: 3 ). |
Finding datasets
I find the following websites helpful for finding datasets:
-
PhysioNet: An invaluable collection of physiological datasets, many of which contain physiological signals such as the ECG.
-
Google Dataset Search: A helpful search engine.
