[The dependability of noninvasive stroke volume measurements with impedance cardiography].
In 33 patients 110 comparative measurements of stroke volume were performed by the thermodilution method and impedance cardiography during rest and various hemodynamic interventions. Agreement was moderate not allowing accurate estimation of the stroke volume in an individual patient. However, impedance cardiography proved useful in predicting acute changes in stroke volume or cardiac output exceeding 10% of control values.
