Abstract

The intent of this thesis is to lay groundwork for examining the relationship between seismocardiography (SCG) and phonocardiography (PCG). Both are methods of measuring and describing heart mechanical function. SCG is described as chest vibrations while the heart beats, and PCG is described as acoustic chest surface signal believed to represent the heart valves opening or closing. SCG and PCG have both been used separately in clinical and research settings, but there is currently no clear comparison between the two. Therefore, there has been no way at the present to understand how one signal might inform the other. This study is an effort to fill that gap. SCG and PCG sensors were placed on subjects’ chests while sensor output was simultaneously recorded. The magnitudes of the signals and their trends were then compared against each other to see their similarities and differences. The comparisons demonstrated similar trends between the two sensor types, supporting the hypothesis that there is a relationship between the two that requires further research and insight.
