Nonexercise Estimation of V̇O2peak Using Seismocardiography in Female Subelite and Male Elite Football Players [PDF]

European Journal of Sport Science
A novel method for estimating V̇O2peak using seismocardiography (SCG eV̇O2peak) at rest was developed some years ago, and this study investigates an updated version using data from a trained population.

Seismocardiography-Based Cardiac Computed Tomography Gating Using Patient-Specific Template Identification and Detection

IEEE Journal of Translational Engineering in Health and Medicine, 2017
To more accurately trigger cardiac computed tomography angiography (CTA) than electrocardiography (ECG) alone, a sub-system is proposed as an intermediate step toward fusing ECG with seismocardiography (SCG).
