Journal ArticleDOI
Studies Made by Simulating Systole at Necropsy VII. Clinical Methods for Estimating the Work of the Left Ventricle. With a Note on the Diminution of Heart Work as Age Advances
TL;DR: A method of approximating the left ventricular work has been devised which is so simple that it could be used by any doctor practising medicine.
Journal ArticleDOI
Studies made by simulating systole at necropsy. XI. On the higher dynamic functions of the heart, and their reflections in the pulse wave.
TL;DR: This paper is chiefly concerned with the development of a simple method, available to clinicians, which would aid in the detection of changes in the acceleration of the aortic blood, and which has also been used to answer certain criticisms of the previously published work.
Journal ArticleDOI

Journal ArticleDOI
A comparison between ultralow-frequency ballistocardiograms and those secured by an improved high-frequency technique, with studies to explain remaining differences.
Isaac Starr,Abraham Noordergraaf +1 more
TL;DR: The advance in ballistocardiographic instrumentation which has been so rapid and so encouraging in recent years has been due primarily to the use of certain physical principles, but on the assumption that well-known physical formulae could be properly applied to the vibration problems of the human body, a new viewpoint emerged.
