May aid noninvasive identification of multivessel CAD on exercise testing; extends ICG validation but leaves open diagnostic utility.
Does automated impedance cardiography (ICG) accurately detect ischemic left ventricular dysfunction during exercise testing in patients with suspected CAD?
Automated impedance cardiography is a feasible noninvasive method to monitor hemodynamics during exercise testing and can help identify patients with multivessel CAD.
Scherhag et al. (2005) studied this question.
