Summary The relationship between stroke volume (SV) measured simultaneously by impedance cardiography (SV1) and echocardiography (SVE) has been analyzed. Change in stroke volume in 6 healthy volunteers was induced by passive head-up tilting (80°) and by oral administration of the sympathomimetic drug amezinium. A correlation ofr=0.83 (p j 0.01) was found between SVI and SVE calculated by the equation: SVE=16.0+(0.528×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.
