Left ventricular tract velocity–time integral (LVOT VTI, yellow boxes) and minute distance (LVOT × heart rate (HR, white boxes)) for assessing the stroke volume (SV) and cardiac output (CO) and their changes with treatments in a patient with cardiogenic shock. a Before treatment. b Receiving 10 ucg/kg/min of dobutamine. There is a marked increase in the LVOT VTI and minute distance after treatment, indicating an improvement in the SV and CO
