Abstract

Impedance cardiography (ICG) is a simple and inexpensive technique for non-invasive and continuous measurement of stroke volume and other hemodynamic parameters. In this method, an estimation of the changes in the aortic blood volume is obtained via measuring the electrical impedance of the thorax area during the cardiac cycle. In comparison to thermo-or dye-dilution methods, impedance cardiography has the inherent advantages of being non-invasive, simple and inexpensive. Compared to the non-invasive methods such as Doppler-echocardiography, the method does not require an expert to perform the test, and can be used for continuous measurement, and even during activity. Impedance cardiography is becoming increasingly used in research and clinical applications. A brief description of the research applications of the impedance cardiography method is given in this letter, and preliminary results of evaluation of an impedance cardiography system developed by the authors are reported.Keywords: Hemodynamic parameters, Impedance cardiography
