Dynamics of nitroglycerin-induced changes in vena cava flows and right atrial pressure.
In anesthetized cats, nitroglycerin increased blood flow in the superior vena cava and decreased the flow in the inferior vena cava and total venous return. Simultaneous changes in right atrial pressure could be either positive or negative. The shifts in the superior vena cava flow and right atrial pressure preceded the corresponding alterations in the inferior vena cava flow and venous return.
