Cardiac Output Can Be Changed Only By Altering Either The Cardiac Or The Venous Function Curve

Effect of Changing Contractility

In Fig. 5, stimulation of the cardiac sympathetic nerves has shifted the cardiac function curve upward and to the left as a result of increased ventricular contractility and heart rate. As predicted (see Chapter 13) this results in a greater cardiac output for any given filling pressure.

FIGURE 5 Effect of cardiac sympathetic nerve stimulation on the cardiovascular state as depicted on a simultaneous plot of the cardiac and vascular function curves.
