Figure 2From: Effect of changes in contractility on the index of myocardial performance in the dysfunctional left ventricleThe effect of dobutamine infusion on IMP with chronic LV dysfunction: The IMP is plotted for each dog (y axis) at paced LV dysfunction (LV Dys) and following infusion of dobutamine (LV Dys-Dob). With dobutamine infusion, each dog demonstrated a decline in IMP.Back to article page
