Frontiers in Cardiovascular Medicine, 2023 BackgroundHeart failure (HF) remains a major cause of mortality, morbidity, and poor quality of life. 44% of HF patients present impaired left ventricular ejection fraction (LVEF). Kinocardiography (KCG) technology combines ballistocardiography (BCG) and

Academic Medicine, 1953 In this study, the normal ballistocardiogram is interrelated with various cardiac events in order to establish the origin of its component waves. It is apparent that the ballistic F, G, H, I, J, K, L, M and N waves bear a definite relationship to known cardiac events, although in some cases the temporal positioning of the complexes is shifted by ...

Optimization and evaluation of a mobile IMU-based ballistocardiography system
Current Directions in Biomedical Engineering, 2023 In recent decades ballistocardiography (BCG) has regained popularity as a way to measure the mechanical activ- ity of the heart. In this paper we present and evaluate a new iteration of our mobile BCG measurement system.

Performance Evaluation of a Smart Bed Technology against Polysomnography
Sensors, 2022 The Sleep Number smart bed uses embedded ballistocardiography, together with network connectivity, signal processing, and machine learning, to detect heart rate (HR), breathing rate (BR), and sleep vs. wake states. This study evaluated the performance of

Healthcare Technology Letters, Volume 10, Issue 6, Page 133-138, December 2023., 2023 Abstract Post‐traumatic stress disorder (PTSD) is an anxiety condition caused by exposure to severe trauma. It is characterised by nightmares, flashbacks, hyper‐vigilance and avoidance behaviour. These all lead to impaired functioning reducing quality of life. PTSD affects 2–5% of the population globally.
