Contactless seismocardiography via deep learning radars [PDF]
Proceedings of the 26th Annual International Conference on Mobile Computing and Networking, 2020 The seismocardiogram (SCG) is a recording of a human heart's mechanical activity. It captures fine-grained cardiovascular events such as the opening and closing of heart valves and the contraction and relaxation of heart chambers. Today, SCG recordings are obtained by strapping an accelerometer at the apex of the heart to measure chest wall vibrations.

Advanced Science, Volume 10, Issue 31, November 3, 2023., 2023 The need for continuous, non‐invasive and real‐time monitoring of cardiovascular vital signs is of primary importance. This requires human‐friendly wearable sensor systems that can be easily and conformably integrated onto the human body. Organic electronic devices may fulfill all those properties.

Estimation of cardiorespiratory fitness in healthy using seismocardiography. [PDF]
NPJ Cardiovasc HealthAbstract Cardiorespiratory fitness expressed as maximal oxygen consumption (V̇O2max) is a strong predictor of cardiovascular health, but its measurement through cardiopulmonary exercise (CPX) testing is complex and costly. This study develops and validates an algorithm for non-exercise estimation of V̇O2max using seismocardiography (SCG-V ...

Forcecardiography: A Novel Technique to Measure Heart Mechanical Vibrations onto the Chest Wall
Sensors, 2020 This paper presents forcecardiography (FCG), a novel technique to measure local, cardiac-induced vibrations onto the chest wall. Since the 19th century, several techniques have been proposed to detect the mechanical vibrations caused by cardiovascular ...

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

International Journal of Endorsing Health Science Research, 2013 Cardiac rate analysis is constituted as one of the most essential parts of physiological patient monitoring. In this research paper, it has been investigated that electrical impedance plethysmography is the most conducive technique for this purpose.

Seismocardiography as a tool for assessment of bi-ventricular pacing
Physiological Measurement, 2022 Abstract Objective. Conduction-induced heart failure in patients with left bundle branch block (LBBB) can benefit from cardiac resynchronization therapy (CRT). However, some patients are non-responders to the therapy with one contributing factor being poor optimization of the atrioventricular ...
