Evaluation of Fluid Resuscitation in Shocked Patients by Electrical Cardiometry in Comparison to Transthoracic Echocardiography.

"Electrical cardiometry (EC) measurements: by the ICON\_ hemodynamic monitor (ICON Cardiotropic, Inc., La Jolla, CA 92307; Osyka Medical GmbH, Berlin, and Germany, model C3).~Transthoracic echocardiography (TTE) measurements will be performed equipped with echo probe. SV of the left ventricle will be calculated using LVOT diameter (D) just below the aortic valve from parasternal long-axis view and VTI measured in LVOT from apical 5 chamber view (by pulsed wave Doppler)."
