Comparison of impedance cardiography with invasive hemodynamic measurements in patients with heart failure secondary to ischemic or nonischemic cardiomyopathy

      Right-sided cardiac catheterization is frequently performed in patients with heart failure despite potential complications including arrhythmias, right ventricular or pulmonary artery perforation, pulmonary infarction, infection,

      A noninvasive measure of cardiac output and left ventricular filling pressures would therefore be desirable. Impedance cardiography via a commercially available device (BioZ.com, CardioDynamics International Corporation, San Diego, California) may permit such noninvasive measurement of hemodynamics by assessing the change in impedance of an alternating current applied across the thorax to determine stroke volume, cardiac output, and thoracic fluid content.

      However, it is not known how well its assessment of cardiac output or thoracic fluid content compares with cardiac output or pulmonary arterial wedge pressure obtained via right-sided cardiac catheterization in patients with heart failure.
