Key result
Review identifies 5 public seismocardiographic datasets limited by heavy bias toward healthy male subjects.
Why the study?
Cardiovascular research is affected by the availability of open databases, motivating a summary of publicly available signal databases with seismocardiographic signals as of January 2023.
This review identifies five publicly available seismocardiographic databases, highlighting current limitations such as gender bias and a lack of data from subjects with cardiovascular diseases.

Existing SCG databases risk biased findings in women and CVD; leaves open development of diverse public datasets for equitable research.
The development of information and communication technologies (ICT) changed many aspects of our lives, including cardiovascular research. This area of research is affected by the availability of open databases that can help conduct basic and applied research. In this study, we summarize the current state of knowledge in publicly available signal databases with seismocardiographic (SCG) signals in January 2023. Based on Google search results for the expression "seismocardiography dataset", we have found and described five databases with seismocardiograms, including three databases that contain SCG signals from healthy subjects, one database with data from porcine subjects, and one signal database with data obtained from human patients with valvular heart disease (VHD). All contain additional signals for reference points in the cardiac cycle. The most significant limitations of the described data sets are gender bias toward male subjects, the imbalance between healthy subjects, and subjects with two cardiovascular diseases (VHD and hemorrhage).

Sieciński et al. (2023) conducted a review in Seismocardiography. A search for publicly available seismocardiographic databases identified five datasets, which are limited by gender bias toward males and an imbalance between healthy and diseased subjects.
