Stroke Volume, Ejection Fraction and Cardiac Health Monitoring using Impedance Cardiography

In recent years occurrence of cardiac ailments have seen an exponential rise. In view of this it is highly important to monitor one's cardiac health. Currently employed methods for cardiac health monitoring are costly, require expert supervision and are available only at central hospitals. In order to overcome these obstacles, we have proposed a novel, non-invasive, cardiac health monitoring mechanism based on Impedance Cardiography (ICG). In this work we have proposed a methodolgy for determination of stroke volume (SV), left ventricular ejection fraction (LVEF), left ventricular end systolic volume (LVESV), and iso-volumetric relaxation time (IVRT), based on ICG. The proposed models report r2 values of 0.86, 0.97, 0.99, and 0.96 for SV, LVESV, LVEF, and IVRT, respectively. The proposed methodology also provides us an insight into the use of ICG for cardiac health monitoring, and diagnosis of critical cardiac ailments.
