Dataset collection
ECG datasets with synchronized PPG
Public ECG datasets that also record PPG, accelerometry or other wearable signals. Compare subjects, sampling, reference labels and licence in one table.
These datasets record an electrocardiogram alongside at least one other physiological channel, most often PPG. Paired ECG makes them the usual choice for validating PPG heart rate, inter-beat intervals, HRV and arrhythmia detection, because R-peaks give a beat-level reference.
ChatPPG lists 117 datasets in this collection. Of the 93 that report participant counts, the median is 45 subjects and the largest has 160,000. The most common recorded signals are PPG (80), accelerometry (41), respiration (39) and EDA (17). Typical research tasks: atrial fibrillation (26), cuffless blood pressure (25), heart rate estimation (24) and SpO2 (15). 76 provide raw waveforms and 47 state a licence.
