Paper Abstract

A device for the recording of the photoplethysmographic (PPG) signal, which filters the dc value without distorting the pulse shape, was developed. PPG measurements were performed on the finger of the left hand while the right hand exerted a static muscle stress. The amplitude and the period of the PPG signal decreased when the other hand was raised to above heart level, and when it exerted a handgrip stress. These effects are associated with increased activity of the sympathetic nervous system.
