Prediction of ECG signals from ballistocardiography using deep learning for the unconstrained measurement of heartbeat intervals. [PDF]

Sci Rep
We developed a deep learning–based extraction of electrocardiographic (ECG) waves from ballistocardiographic (BCG) signals and explored their use in R–R interval (RRI) estimation.

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.

Study on Multimodal Sensor Fusion for Heart Rate Estimation Using BCG and PPG Signals [PDF]

Sensors
Continuous heart rate monitoring is crucial for early cardiovascular disease detection. To overcome the discomfort and limitations of ECG in home settings, we propose a multimodal temporal fusion network (MM-TFNet) that integrates ballistocardiography ...

Non-contact assessment of cardiac physiology using FO-MVSS-based ballistocardiography: a promising approach for heart failure evaluation. [PDF]

Sci Rep
Continuous monitoring of cardiac motions has been expected to provide essential cardiac physiology information on cardiovascular functioning. A fiber-optic micro-vibration sensing system (FO-MVSS) makes it promising.

Changepoint Detection in Heart Rate Variability Indices in Older Patients Without Cancer at End of Life Using Ballistocardiography Signals: Preliminary Retrospective Study. [PDF]

JMIR Form Res
Background In an aging society such as Japan, where the number of older people continues to increase, providing in-hospital end-of-life care for all deaths, and end-of-life care outside of hospitals, such as at home or in nursing homes, will be difficult.

Identifying Gravity-Related Artifacts on Ballistocardiography Signals by Comparing Weightlessness and Normal Gravity Recordings (ARTIFACTS): Protocol for an Observational Study.

JMIR Res Protoc
Background Modern ballistocardiography (BCG) and seismocardiography (SCG) use acceleration sensors to measure oscillating recoil movements of the body caused by the heartbeat and blood flow, which are transmitted to the body surface.

A Comparison of Ballistocardiography and Conventional Bedside Monitors for Measurement of Vital Parameters [PDF]

Indian J Crit Care Med
Introduction Ballistocardiography is a technique of contactless monitoring of the body's basic vital parameters. (1) During left ventricular systole, downward acceleration of the blood through the aortic arch produces an upthrust of the body, and during ...

Non-obtrusive monitoring of obstructive sleep apnea syndrome based on ballistocardiography: a preliminary study [PDF]

Frontiers in Neuroscience
IntroductionObstructive sleep apnea syndrome (OSAS) degrades sleep quality and is associated with serious health conditions. Instead of the gold-standard polysomnography requiring complex equipment and expertise, a non-obtrusive device such as ...
