Best PPG datasets for blood pressure estimation
These datasets pair PPG with a blood pressure reference, either an arterial line or a cuff. Invasive references such as VitalDB and the MIMIC-III matched subset give beat-level targets; cuff datasets such as PPG-BP are smaller but closer to how a wearable would be calibrated. Each card shows the reference type, subject count and license so you can pick a calibration-free or calibration-based setup before you download anything.
