The Three Directional Ballistocardiogram on Experimental Coronary Stenosis and Occlusion of the Dog

概要

An attempt was made to pursue the development of ballistocardiographic abnormalities in human cases of coronary artery diseases. For that purpose, ballistocardiographic changes on experimental coronary stenosis and occlusion produced by a left coronary catheterization and infusion of several substances were observed on 44 dogs by a newly designed three directional ballistocardiograph. Abnormal patterns clinically observed in cases with coronary artery diseases were demonstrated on dogs with experimental coronary stenosis or occlusion. The difference on ballistocardiographic changes in cases with circumflex segment occlusion from those in cases with anterior descending branch occlusion is very likely to be related to the difference on a 'localized' decrease of myocardial contraction other than arterial blood pressure or venous return.
