Estimation of aortic stiffness by finger photoplethysmography using enhanced pulse wave analysis and machine learning

Frontiers in Cardiovascular Medicine

Photoplethysmography (PPG) and single-lead electrocardiogram (ECG) are readily available in healthcare and wearable devices. We extracted 136 established PPG waveform features and engineered 13 new with improved coupling to the finger blood pressure curve. Height-normalized pulse arrival time (NPAT) was derived using ECG.
