The Abnormal Ballistocardiogram in Mitral Stenosis
The Relationship of the Abnormal Waves to Right Ventricular Ejection and to the Mean Pulmonary Artery Pressure
Two abnormal waves present in the ballistocardiograms of 100 cases of mitral stenosis are described and the abnormality is classified into five grades. Evidence is presented which indicates that the abnormal waves are a result of ejection from the right ventricle and that the degree of abnormality of the ballistocardiogram bears a close relationship to the mean pulmonary artery pressure in mitral stenosis.
