Transthoracic electrical bioimpedence cardiac output: comparison with multigated equillibrium radionuclide cardiography.

Introduction: Thoracic electrical bioimpedance (TEB) for measuring cardiac output (CO) is being explored increasingly as an alternative to pulmonary artery catheter. The major advantage of this technology is that it is non-invasive and easy to perform. Several studies have compared it to thermodilution cardiac output using PA catheter, with variable correlation.
