Ultrasound and Left Ventricular Systolic Function

Fondation Ophtalmologique Adolphe de Rothschild100 enrolled

Overview

The aim of this study is to evaluate, in an intensive care unit, the reproducibility between two non-cardiologists operators and a cardiologist expert in echocardiogram, of the Simpson method and of the calculation of GLS for the evaluation of the systolic function of the left ventricle in critically ill patients intubated and ventilated.
