Calibration of the Direct Ballistocardiogram [PDF]

Circulation, 1953
A simple method of calibrating the amplitude of the direct ballistocardiogram, utilizing a standard external force to the body, is described. Such a method tends to neutralize many of the variables in apparatus alignment and sensitivity, and provides a basis for comparison of amplitudes in the same and different subjects.

Ballistocardiogram in Chronic Severe Anemia [PDF]

Circulation, 1959
Serial ballistocardiograms of 30 patients with chronic severe anemia were studied to assess the cardiovascular state in anemia and after the cure of anemia. The findings in the ballistocardiogram have been compared to those in the electrocardiogram and the roentgenogram.
