Key result
A home-made multi-channel PPG-ECG device allowed estimation of arterial stiffness at multiple body locations without supra-systolic cuff occlusion.
Why the study?
Combined ECG and PPG can quantify arterial stiffness, and the capabilities of a home-made multi-channel PPG-ECG device to evaluate arterial ageing needed assessment.

Can a multi-channel PPG-ECG device estimate arterial stiffness without supra-systolic cuff occlusion?
A novel multi-channel PPG-ECG device can estimate arterial stiffness at multiple body locations without cuff occlusion, potentially enabling large-scale cardiovascular risk screening.
Photoplethysmography (PPG) is a non-invasive technique that employs near infrared light to estimate periodic oscillations in blood volume within arteries caused by the pulse pressure wave. Importantly, combined Electrocardiography (ECG) and PPG can be employed to quantify arterial stiffness. The capabilities of a home-made multi-channel PPG-ECG device (7 PPG probes, 4 ECG derivations) to evaluate arterial ageing were assessed. The high numerosity of channels allowed to estimate arterial stiffness at multiple body locations, without supra-systolic cuff occlusion, providing a fast and accurate examination of cardiovascular status and potentially allowing large scale clinical screening of cardiovascular risk.
