Calibrating Cardiac Output Measurement of Electrical Cardiometry With Transthoracic Echocardiography

Summary

Cardiac output (CO) is a key variable when describing the cardiovascular system. Electrical cardiometry (EC) is a non-invasive method in measuring stroke volume and cardiac output. However, its accuracy has been inconsistent. Therefore Martin et al. have compared measurements with echocardiographic measurements and propose calibration with left ventricle outflow tract (LVOT)-measurements obtained from transthoracic echocardiography (TTE). This study was performed in pregnant women at term. Goal of this study is to validate their formula in non-pregnant outpatients undergoing echocardiography for cardiology work-up. Secondary aim is to perform a leg raising test and to compare changes in stroke volume observed with either EC or TTE.

Conditions

Interventions

OTHER

passive leg raising test

Patients undergoing routine echocardiography are exposed to a passive leg raising test. Change in SV will be measured by TTE and compared to changes in SV measured by EC.

PROCEDURE

right heart catheterisation

CO in patients undergoing routine right heart catheterisation will be measured and compared between 3 methodologies: right heart catheterisation, TTE and EC

OTHER

TTE vs. EC + calibration group

Patients will undergo routine echocardiography. CO and SV will be measured by TTE and compared to measurements obtained from simultaneous EC-measurements.
