Assessing the response to vascular filling in shock is a challenge in emergency medicine. The mitral annulus velocity measured by tissue Doppler (E') has recently been characterized as sensitive to the preload conditions of a patient. The investigators hypothesize that the E' variation (∆E') before and after fluid filling allows us to assess the response to vascular filling. The investigators hypothesize that the ∆E' has a good diagnostic performance to establish whether a patient is responsive to fluid filling, defined by an area under the ROC curve greater than 0.75.
