Description
Summary:Quantitative seismocardiography is a simple and non-invasive method of measuring compression waves generated by heart activity. It provides important information about the cardiovascular system. The first important information acquired from quantitative seismocardiogram (QSCG) is the pseudo-period rate. This paper focuses just on the detection of pseudo-periods in the QSCG signal. Two methods of detection together with a method of sophisticated data preprocessing are presented. The results of the methods are demonstrated using real data.
