Do changes in impedance cardiography parameters correlate with changes in ejection fraction in patients with heart failure?
Changes in impedance cardiography parameters correlate highly with changes in ejection fraction, suggesting it may be a practical and cost-effective noninvasive method for monitoring left ventricular function in heart failure.
Parrott et al. (2004) studied this question.
