Groups/Cohorts Assigned Interventions
Healthy volunteers
Healthy volounteers with no previous medical history, age between 20-40. Both male and female. Subjects are provided extensive information about the study and the obligations and expectations included. All subjects sign a witnessed informed consent before inclusion.
Procedure: Arterial waveform analysis, esofageal doppler, transthoracal cardiac ultrasound, Cardiac magnetic resonance imaging.
Other Names:
  • Vigileo/FloTrac, Edward Lifesciences (arterial waveform analysis)
  • CardioQ, Deltex medical (esofageal doppler)
  • Philips, Magnetic Resonance Imaging
  • Vivid S6, GE, Cardiac ultrasound

Detailed Description:

20 healthy volounteers between age of 20-40 years, no previous medical history undergo simoultaneous left ventrikular strokevolume measurements using three different methods at rest. After datasampling and without moving, the subject then undergo Cardiac Magnetic Resonance Imaging with 2D-throughplane and cine tecnology for validation of volume measurements. The data is then analyzed using Bland-Altman calculation.
