Abstract
In this paper we demonstrate that SCG can be used to estimate hemodynamic parameters such as stroke volume and the three systolic time intervals of pre-ejection period (PEP), left ventricular ejection time (LVET) and electromechanical systole (QS2).In this study, recordings of suprasternal pulsed Doppler and Impedance cardiogram (ICG) were used as the reference methods for comparison to the values estimated by SCG. Simultaneous SCG and ICG and Doppler were recorded from twenty four participants.
