Figure 6 One representative dog showing intraventricular diastolic pressure gradients between the left ventricular (LV) mitral and apical regions at baseline (upper panel), after induction of acute LV failure by microembolization (middle panel), and during isoprenaline (lower panel). The LV inflow tract pressure gradient is indicated by the vertical lines, and its peak at baseline, during LV failure, and isoprenaline is 2.6, 1.4, and 5.3 mm Hg, respectively. LVP = pressure in the left ventricle.
