Impedance cardiography: a bridge between research and clinical practice in the treatment of heart failure.

Abstract

This paper proposes that impedance cardiography could narrow the gap between heart failure clinical research and the appropriate and timely application of new knowledge and technology in the care of patients with heart failure. Research variables and measurement strategies, identified in the heart failure scientific literature between 1994-1999, are compared to measures that can be obtained through a cost effective, noninvasive technology--impedance cardiography. Emphasis is placed on case reports that illustrate how "real time" evaluation and trending of key hemodynamic variables through impedance cardiography monitoring has been used to apply state of the science knowledge and technology to improve the inpatient and outpatient management of care for patients with severe heart failure.
