MIMIC PERform AF Dataset
This dataset contains ECG and PPG recordings of 20-minute duration, some of which were acquired during atrial fibrillation (AF), and the rest were acquired during normal sinus rhythm.
Overview
| Item | Details |
|---|---|
| Links | Dataset, Publication |
| Signals | PPG, ECG, respiration |
| No. Subjs | 35 (19 in AF, 16 not in AF) |
| Protocol | 35 critically-ill adults during routine clinical care. Data were measured using a bedside monitor at 125 Hz. Manual labels of AF and non-AF subjects were obtained from here, as described in [1]. Data were extracted from the MIMIC-III Waveform Database Matched Subset. |

Recreating the dataset
The dataset can be recreated from scratch by taking the following steps:
- Download the following MATLAB script:
collate_mimic_perform_af_dataset. - Modify the MATLAB script by inserting the
up.paths.root_folderandup.paths.save_folderinto thesetup_upfunction. - Note: The duration of recordings provided by the script can be adjusted with the
up.settings.req_durnvariable within thesetup_upfunction. - Run the MATLAB script to download the required files from PhysioNet, import the data into MATLAB, and collate the data into a single MATLAB data file, ready for analysis.
