Studies Utilizing the Portable Electromagnetic Ballistocardiograph
III. The Ballistocardiogram in Bundle Branch Block
Ballistocardiographic studies were done on 28 subjects with left bundle branch block and on 18 subjects with right bundle branch block. The influence of ventricular asynchronism, and the predominance of left or right ventricular disease, upon the derivation and interpretation of the ballistocardiogram, is discussed. The ballistocardiogram was found to be a valuable objective guide in the detection of subjects whose bundle branch block was not associated with significant heart disease. The ballistocardiogram also provided helpful confirmatory evidence of coronary artery or hypertensive heart disease when this was the suspected or certain diagnosis in subjects with bundle branch block.
