Contactless seismocardiography via deep learning radars [PDF]

Proceedings of the 26th Annual International Conference on Mobile Computing and Networking, 2020
The seismocardiogram (SCG) is a recording of a human heart's mechanical activity. It captures fine-grained cardiovascular events such as the opening and closing of heart valves and the contraction and relaxation of heart chambers. Today, SCG recordings are obtained by strapping an accelerometer at the apex of the heart to measure chest wall vibrations.

Seismocardiography on Infants and Kids

Computing in Cardiology Conference (CinC), 2020
Seismocardiography (SCG) offers a variety of possibilities for cardiovascular diagnostics, especially in long-term monitoring. Unfortunately, little information is available about changes in SCG-signal-morphology over the life course, as well as differences in different age groups.
