Wrist ballistocardiography and invasively recorded blood pressure in healthy volunteers during reclining bike exercise

Frontiers in Physiology, 2023
Objective: Ballistocardiogram (BCG) features are of interest in wearable cardiovascular monitoring of cardiac performance. We assess feasibility of wrist acceleration BCG during exercise for estimating pulse transit time (PTT), enabling broader ...

Psychosocial stressors in psychosomatic cardiology: A narrative review

Heart and Mind, 2022
The definition of a psychosocial stressor and reactions to it is discussed in relation to individual and environmental factors. The relation of this model to psychophysiological stress reactions and regeneration, as well as its significance for ...

Mechanism-Driven Modeling to Aid Non-invasive Monitoring of Cardiac Function via Ballistocardiography

Frontiers in Medical Technology, 2022
Left ventricular (LV) catheterization provides LV pressure-volume (P-V) loops and it represents the gold standard for cardiac function monitoring. This technique, however, is invasive and this limits its applicability in clinical and in-home settings ...

Investigating Cardiorespiratory Interaction Using Ballistocardiography and Seismocardiography—A Narrative Review

Sensors, 2022
Ballistocardiography (BCG) and seismocardiography (SCG) are non-invasive techniques used to record the micromovements induced by cardiovascular activity at the body’s center of mass and on the chest, respectively.

Ballistocardiography [PDF]

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 ...

Non-invasive cardiac kinetic energy distribution: a new marker of heart failure with impaired ejection fraction (KINO-HF)

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

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.

Monitoring of Cardiorespiratory Parameters during Sleep Using a Special Holder for the Accelerometer Sensor

Sensors, 2023
Sleep is extremely important for physical and mental health. Although polysomnography is an established approach in sleep analysis, it is quite intrusive and expensive.

Neurotechnological solutions for post‐traumatic stress disorder: A perspective review and concept proposal

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.
