The Elimination of Body Resonance Distortion from the Direct-Body Ballistocardiogram
A simple method of obtaining a force ballistocardiogram has been presented. This type of tracing has been derived from the direct-body ballistocardiogram by electrically filtering out body resonance distortion. The resultant force tracings appear to be closely related to cardiovascular events.
