Changes in Cardiac Output with Age
TL;DR: A substantially reduced output was a consistent finding in older subjects and one result of the analysis of time-concentration curves of dye provides an interesting relationship to clinical estimates of circulation time.

Twenty-Year Studies with the Ballistocardiograph
Isaac Starr,Francis C. Wood +1 more
TL;DR: A group of 211 healthy persons, gathered together from 23 to 17 years ago to provide normal standards for the ballistocardiograms, has been followed to the present time, finding the normal rate of cardiac decline, as age advances, agrees closely with that calculated for several bodily functions.

Some technics for recording the ballistocardiogram directly from the body
William Dock,Felix Taubman +1 more
TL;DR: The motion of the body recorded by a sphygmograph applied to the head, by a photocell partly shaded by a ruler across the shins, or by a coil in a magnetic field provides a satisfactory ballistocardiogram.
Journal ArticleDOI
Rapid Assessment of Cardiac Contractility on a Home Bathroom Scale
TL;DR: The RJ interval, the time delay between the J-wave peak of the BCG and the R-wave of the ECG, was correlated to PEP and suggests that the RJ interval can be reliably used as a noninvasive assessment of cardiac contractility.
