The synthetic dataset is a collection of simulated electrocardiogram (ECG) and pulse oximetry (photoplethysmogram, PPG) signals. The signals were generated to allow researchers to check that their algorithms are able to estimate respiratory rate (RR) accurately on idealised data. It is particularly helpful for ensuring that algorithms are reasonably implemented.


The dataset contains ECG and PPG signals across covering a range of heart rates (HRs) and RRs. Three signals are provided for each combination of HR and RR, each exhibiting either baseline wander (BW), amplitude modulation (AM), or frequency modulation (FM).

The dataset is provided in Matlab format. Firstly, the source code used to generate the dataset is provided (here). This allows users to modify the dataset to their own liking. Secondly, the dataset is provided having used a particular configuration of the source code to produce it (below).


Exemplary Synthetic Signals: Idealised PPG and ECG signals are shown on the top row. On the three subsequent rows are idealised signals modulated with Baseline Wander (BW), Amplitude Modulation (AM) and Frequency Modulation (FM). Adapted from:
