Possibilities of Foucault cardiography-based estimation of heart pumping performance

Abstract

Foucault cardiogram (i.e. magnetic induction cardiogram / eddy currents cardiogram) is expected to represent the ventricular volume in a scale that is individual for a patient. Thus, it would be used to estimate physiological characteristics that are determined by relative values of ventricular volume or a ratio of the ventricular volume values. There is a concept of ventricular pumping performance derived from Starling's heart law. The ventricular pumping performance can be evaluated from the ventricular volume data and it would be just a quantity for which the calculation needs only relative values of that volume. This approach for the estimation of ventricular pumping performance has been studied and its results are discussed. © Springer-Verlag 2007.
