Cardiovascular Monitoring by Seismocardiography

Seismocardiography (SCG) is a non-invasive method to monitor 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 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. 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. In the second part of the talk, I will discuss our progress in estimating cardiac time intervals from the SCG signals. Overall, our goal is to improve patient outcomes and quality of life through developing accurate and robust cardiovascular monitoring systems.
