Summary

Electric Impedance Tomography (EIT) is a technique based on the injection of small currents and voltage measurements using electrodes on the skin surface generating cross-sectional images representing impedance change in a slice of the thorax.It is a radiation free, non- invasive and portable lung imaging technique. Impedance changes in lung ventilation as well as in lung perfusion can be shown. To investigate lung perfusion by EIT measurements, cardiac output measured by routinely undergone stress echocardiography at rest and stress are compared to parameters measured by EIT.

Conditions

  • Electric Impedance Tomography
  • Stress Echocardiography
  • Cardiac Output
  • Ventilation
  • Perfusion

Interventions

DEVICE

EIT (Electrical Impedance Tomography)

EIT measurement; concomitant to stress echocardiography (about 45 minutes) EIT measurements (1 minute) are performed at rest, at low dobutamine stress, at peak and at relaxation
