Development of a bedrest muscle stress apparatus [PDF]

, 1979
In attempting further to define the deleterious effects of spaceflight on the human body, measurement systems and techniques were devised to determine the loss of skeletal muscle strength and tone as a result of spaceflight exposure.

Augmented Phonocardiogram Acquisition and Analysis [PDF]

, 2011
Heart auscultation (the interpretation of heart sounds by a physician) is a widely used screening method for heart disease. It is well documented, however, that with the exception of expert cardiologists, physicians' auscultation skills are limited. It has also been shown that standard training methods do little to improve these skills.

Ensemble Voting Method for Phonocardiogram Heart Signal Classification Using FFT Features

Journal of Applied Informatics and Computing
Heart disease is still one of the leading causes of death worldwide, hence the need for effective diagnostic tools. Phonocardiogram (PCG) signals have been explored as a complementary approach to electrocardiogram (ECG) to detect cardiac abnormalities ...

Fog-Enabled Multimodal Chest-Worn Device for Systolic Blood Pressure Monitoring

IEEE Access
This paper presents a Fog-enabled chest-worn device for estimating systolic blood pressure (SBP). The device integrates two sensors that simultaneously detect the phonocardiogram (PCG), ballistocardiogram (BCG), and seismocardiogram (SCG) from a single ...

HEMODYNAMIC CORRELATION WITH PHONOCARDIOGRAM IN AORTIC INSUFFICIENCY

Japanese Circulation Journal, 1972
Phonocardiographic, hemodynamic and angiocardiographic study in thirty two patients with isolated aortic insufficiency or accompanied by other valvular lesions or congenital defects were carried out with special reference to the correlation between configuration of the diastolic murmur and regurgi-tant percent, and between Q-1 interval and end ...
