Figure 3From: Effect of changes in contractility on the index of myocardial performance in the dysfunctional left ventricleEffect of digoxin 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-Dig). With dobutamine infusion, 13 of 14 dogs demonstrated a decline in IMP.Back to article page
