A Unified Methodology for Heartbeats Detection in Seismocardiogram and Ballistocardiogram Signals [PDF]
Computers, 2020 This work presents a methodology to analyze and segment both seismocardiogram (SCG) and ballistocardiogram (BCG) signals in a unified fashion. An unsupervised approach is followed to extract a template of SCG/BCG heartbeats, which is then used to fine ...

Synthetic seismocardiogram generation using a transformer-based neural network. [PDF]
J Am Med Inform Assoc, 2023 Abstract Objective To design and validate a novel deep generative model for seismocardiogram (SCG) dataset augmentation. SCG is a noninvasively acquired cardiomechanical signal used in a wide range of cardivascular monitoring tasks; however, these approaches are limited due to the scarcity of SCG data.
