Abstract

Seismocardiography (SCG) is a non-invasive method to monitor the mechanical activity of the cardiovascular system based on vibrations of the chest surface. This method has shown promise in providing clinically relevant information for cardiovascular diseases such as heart failure and atrial fibrillation. In this presentation, I will present our research progress in developing novel contactless methods to acquire and analyze SCG signals. In the first part of the presentation, I will describe our efforts in developing a vision-based technique to extract chest vibrations associated with SCG from chest videos recorded by a smartphone. SCG signals are conventionally measured using accelerometers attached to the chest. Vision-based techniques can improve the accessibility of this novel cardiovascular monitoring method and make it available to the public given the wide access to smartphones. In the second part of the talk, I will discuss why it is important to carefully select the SCG measurement location on the chest for estimating cardiac time intervals from the SCG signals. Overall, our research goal in this project is to improve patient outcomes and quality of life by developing accurate and robust cardiovascular monitoring methods based on SCG.
