Comparison of impedance cardiography and echocardiography for measurement of stroke volume.

Abstract

The relationship between stroke volume (SV) measured simultaneously by impedance cardiography (SVI) and echocardiography (SVE) has been analyzed. Change in stroke volume in 6 healthy volunteers was induced by passive head-up tilting (80 degrees) and by oral administration of the sympathomimetic drug amezinium. A correlation of r = 0.83 (p much less than 0.01) was found between SVI and SVE calculated by the equation: SVE = 16.0 + (0.528 x SVI). Though stroke volume is overestimated by impedance cardiography, the method may be useful for the clinical pharmacologist interested in a simple non-invasive tool to estimate stroke volume and change in it.
