WebWe begin with a simple hydraulic model for the circulation, with a constant circulating volume. We show, with the help of a modification of Guyton's classic diagram, that cardiac output and mean arterial pressure are functions of circulating volume, peripheral resistance, venous and arterial compliances, and the cardiac Starling curve. WebEffects of Inotropy on Frank-Starling Curves By altering the rate of ventricular pressure development, the rate of ventricular ejection into the aorta (i.e., ejection velocity) is changed. Because there is finite time available for ejection (~200 msec), changes in ejection velocity alter the stroke volume - increased ejection velocity increases ...
