Does impedance cardiography provide clinically acceptable agreement with radionuclide ventriculography for measuring ejection fraction?
Impedance cardiography should not replace radionuclide ventriculography for assessing ejection fraction due to clinically unacceptable limits of agreement.
The 95% confidence range defining the limits of agreement between ejection fraction by impedance cardiography and ejection fraction by radionuclide ventriculography is not clinically acceptable. In the opinion of the authors impedance cardiography should not be used in place of radionuclide ventriculography for the assessment of ejection fraction at this time.
BOWLING et al. (Fri,) studied this question.
