3. Fig. 2
Example of four-chamber echocardiographic images in a patient with a stress-induced new wall motion abnormality with dobutamine infusion. There is normal wall motion at rest (REST, left panel) with the expected decrease in left ventricular (LV) cavity size from diastole (Dias) to systole (Sys). With dobutamine (DOB) stress (right panel), there is dyskinesis of the distal septum in systole (arrow).
