Summary

Real-time comparison of three different bedside strokevolumemeasurements (arterial waveform analysis, eosofageal doppler and 2D transthoracal ultrasound) validated against cardiac magnetic resonance imaging (CMRI)

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.

Conditions

• Difference in Measured Results Using Four Different Strokevolume Measurements Simultaneously.

Interventions

Type	Name	Description
PROCEDURE	Arterial waveform analysis, esofageal doppler, transthoracal cardiac ultrasound, Cardiac magnetic resonance imaging.
