A Novel Non-invasive System for Acquiring Jugular Venous Pulse Waveforms

Abstract

This paper lays the groundwork for the non-invasive acquisition of jugular venous pulse (JVP) waveforms, using accelerometer sensors to measure the vibrations of the jugular vein and the carotid artery. In the cardiac system, the vibrational signals quantify the pressure buildup in the blood vessels due to various hemodynamic events in the cardiac cycle. Accordingly, the accelerometer outputs are suitably amplified, filtered and digitized, so that an appropriate post-processing scheme can be applied to derive the corresponding JVP waveforms. The experimental results show that, even in a preliminary implementation, the JVP waveforms obtained using our proposed system exhibit promising consistency and accuracy, suitable for basic timing analyses of various cardiac parameters. It is anticipated that, with further development and optimization, our proposed system should offer a compelling alternative for clinical diagnoses and applications based on the JVP waveforms, potentially supplanting more complicated methods traditionally used to measure the JVP.
