Feasibility of monitoring congestive heart failure with seismocardiography: a literature review

Abstract

Heart failure, a condition impacting more than 23 million individuals globally, is anticipated to see an increase in its incidence. Among the various types of heart failure, Congestive Heart Failure (CHF) stands out with its hallmark of inadequate blood pumping leading to fluid accumulation in diverse body regions. Monitoring patients afflicted by CHF holds the key to better healthcare outcomes, which include timely medication delivery and reducing rehospitalization. This literature review discusses the feasibility of employing seismocardiography (SCG). SCG is a non-invasive method that relies on accelerometers to record the chest vibrations caused by cardiac activities. SCG's correlation with intracardiac filling pressures has the potential to monitor both healthy individuals and patients with heart failure, thereby reducing readmission. In addition, the integration of SCG with other wearable sensor technologies and machine learning applications can further improve diagnostic accuracy and personalized predictive models for HF progression.
