Severe aortic stenosis detection using seismocardiography. [PDF]
Open HeartBackground Patients with severe aortic stenosis (AS) are at high risk of mortality, regardless of symptom status. Despite this, aortic valve replacement rates remain low for patients with severe AS due to challenges in identifying clinically significant ...

Accelerometer-Based Method for Extracting Respiratory and Cardiac Gating Information for Dual Gating during Nuclear Medicine Imaging [PDF]
International Journal of Biomedical Imaging, 2014 Both respiratory and cardiac motions reduce the quality and consistency of medical imaging specifically in nuclear medicine imaging. Motion artifacts can be eliminated by gating the image acquisition based on the respiratory phase and cardiac ...

The kinocardiograph for assessment of fluid status in patients with acute decompensated heart failure. [PDF]
ESC Heart Fail, 2023 Abstract Aims To improve telemonitoring strategies in heart failure patients, there is a need for novel non‐obtrusive sensors that monitor parameters closely related to intracardiac filling pressures. This proof‐of‐concept study aims to evaluate the responsiveness of cardiac kinetic energy (KE) measured with the Kinocardiograph (KCG), consisting of a ...

A novel broadband forcecardiography sensor for simultaneous monitoring of respiration, infrasonic cardiac vibrations and heart sounds [PDF]
, 2021 The precordial mechanical vibrations generated by cardiac contractions have a rich frequency spectrum. While the lowest frequencies can be palpated, the higher infrasonic frequencies are usually captured by the seismocardiogram (SCG) signal and the ...
