  Purpose
The cardiac output (CO) is an important parameter in the diagnosis and therapy of cardiac diseases. The current standard methods for the determination of the CO, however, are either invasive (e.g. right heart catheterization) or technically expendable and expensive (magnetic resonance tomography, MRT). Therefore the aim of the study at hand was to evaluate the electrical velocimetry technique as a new method for determining the CO and to compare this new technique with the Inert Gas Rebreathing Method and with the Magnetic Resonance Tomography

Condition Intervention
Cardiac Diseases Device: electrical velocimetry Device: inert gas rebreathing Device: spirometry Device: cardiac magnetic resonance imaging (CMR)

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Official Title: Non-Invasive Determination of Cardiac Output by Electrical Velocimetry Compared With Magnetic Resonance Tomography and Inert Gas Rebreathing Method
