Seismocardiography: Past, present and future

2013 35th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2013
This paper presents an overview of seismocardiography (SCG) as a noninvasive cardiology method. The paper represents a brief historical background to the SCG, an assessment of the technology at present, and an evaluation of the challenges we must address.

Seismocardiography while sleeping at high altitude

2012 Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2012
Current advancements in sensor technology allow the prolonged assessment of the seismocadiogram (SCG) out of the laboratory setting. Aim of this study is to evaluate whether SCG, as measured by a recently proposed wearable device, can detect cardio-respiratory alterations during sleep in healthy subjects exposed to high altitude hypoxia.

Seismocardiography-Based Detection of Cardiac Quiescence

IEEE Transactions on Biomedical Engineering, 2015
Cardiac-computed tomography angiography (CTA) is a minimally invasive imaging technology for characterizing coronary arteries. A fundamental limitation of CTA imaging is cardiac movement, which can cause artifacts and reduce the quality of the obtained images.

Timing detection and seismocardiography waveform extraction

2012 Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2012
Described herein is a new and robust method to extract heart-beat timing from seismocardiogram (SCG). This timing indicates the precise time location of each heart beat and therefore directly conveys heart rate information. Knowledge of the time location of each occurrence of the underlying SCG waveform allows us to obtain a clean SCG waveform estimate

Seismocardiography: a technique for recording precordial acceleration

[1991] Computer-Based Medical Systems@m_Proceedings of the Fourth Annual IEEE Symposium, 2002
The methodology for obtaining a recording and the initial findings from the seismocardiography (SCG) technique are described. It is shown that the seismocardiogram contains clearly defined points associated with the cardiac cycle that are correlated by analyzing simultaneous SCG and M-mode and Doppler echocardiograms.

A 3D model of the thorax for seismocardiography

2015 Computing in Cardiology Conference (CinC), 2015
Seismocardiography (SCG) is measurement of sternal acceleration caused by heart beats. Although fiducial cardiac events have been associated with seismocardiogram extrema, the forces that cause the vibrations are unknown. The goal of this study was to create a 3D model of the thorax capable of modelling its vibrations under heart-like forces.

Seismocardiography: Toward heart rate variability (HRV) estimation

2015 IEEE International Symposium on Medical Measurements and Applications (MeMeA) Proceedings, 2015
Heart rate variability (HRV), the variation in the beat-to-beat heart rate, is a key indicator of the cardiovascular condition of an individual. The purpose of this study was to cross-validate the beat-by-beat time variations in seismocardiography (SCG) with electrocardiography (ECG) for determining ultra-short term HRV indices.

Seismocardiography: waveform identification and noise analysis

[1991] Proceedings Computers in Cardiology, 2002
The seismocardiogram (SCG) provides a convenient and reliable measure of left ventricular systolic and diastolic performance both at rest and immediately after exercise. An effective means has been developed to eliminate noise artifacts such as coughing, talking, and patient movement prior to any waveform averaging scheme. A computer algorithm has been
