Studies of Quantitative Ballistocardiography
The Velocity of Body Displacement in Patients with Heart Disease
The speed of body displacement was calculated on 70 per cent of the ballistocardiograms recorded in 128 patients suffering from heart disease. Results show that the values are generally lower in cardliac patients than in normal subjects, with the exception of cases with high stroke volume. The diminution of the speed of body displacement is proportional to the severity of ballistic abnormalities and to the functional state of the heart. A tentative explanation of the findings is presented.
