Acceleration Ballistocardiography

Acceleration ballistocardiography; design, construction, and application of a new instrument.

The construction of a linear accelerometer for use in ballistocardiography is presented including the relationship between acceleration, displacement, and velocity. The sensing element described is new in the field of ballistocardiography, being based on an electrochemical principle. A means of easily calibrating the instrument is described, thereby allowing quantitative measurements of various...

[New trends in ballistocardiography].

Balistocardiography is a method by which body vibrations caused by heart activity are registered. Evolution during the past fifty years to the present is described. Balistocardiography (BCG) represented by instruments of different natural frequencies and damping should bring information about cardiac output. This expectation was not fulfilled due to the unsuitable physical properties of apparat...

Ballistocardiography in the Physics Classroom

Ballistocardiography: predictor of coronary heart disease.

FROM THE early ballistocardiographic (BCG) studies of Starr there developed much hope that the technique would fill an important need in clinical cardiology. Unfortunately the technical deficiencies of certain early methods, their indiscriminate use, and thoughtless interpretation soon caused the method to become clinically discredited in the minds of many people. In spite of this, careful hemo...
