title: Use of ballistocardiography for determining the hyperfunction of the left ventricle.
abstract: A study of patients with patent ductus arteriosus and atrium septum defect, by use ofdirect body Bcg showed that an increased IJ amplitude is due to an increased stroke volume of the left and not of the right ventricle. High IJ amplitude is observed in patients with cardiovascular diseases, causing an increased output of the left ventricle ofover 50% above normal.
