Abstract

Cardiovascular disease continues to be a leading cause of death in the United States, and a source of financial strain on the healthcare system. This prompts the need for new methods of low-cost, noninvasive technologies for cardiac monitoring to improve patient health and reduce healthcare costs. While the first and second heart sounds are common references that are listened to during auscultation of heart, seismocardiography (SCG) is a technology that detects chest sound vibrations with an accelerometer and may offer more information beyond the audible heart sounds. There is currently limited information regarding both the relationship between audible heart sounds and SCG, as well as the low-frequency (<20 >Hz) characteristics of heart sounds. The intent of this thesis is to investigate the relationship between audible heart sounds and SCG, with the goal of understanding the clinical utility of SCG. This was done using both audible and subaudible frequencies. Comparisons indicate the SCG signal carries a greater amount of low-frequency content than audible heart sounds, which warrants further study to determine how SCG can be best harnessed for cardiac monitoring.
