Figure 1From: Left ventricular twist is load-dependent as shown in a large animal model with controlled cardiac load Representative vena cava occlusion sequence is demonstrated in pressure-volume diagrams with the first and last beats in the sequence shown to demonstrate the loading conditions, first at baseline, then as well as during experimentally (pharmacologically) manipulated inotropic conditions, positive inotropic condition (adrenaline) and negative inotropic condition (beta blockade).
