In vivo however, extrinsic factors such as an increase in activity of the sympathetic nerves, and a decrease in vagal tone cause the heart to beat more frequently and more forcefully. This alters the cardiac function curve, shifting it upwards. This allows the heart to cope with the required cardiac output at a relatively … Ver más A cardiac function curve is a graph showing the relationship between right atrial pressure (x-axis) and cardiac output (y-axis). Superimposition of the cardiac function curve and venous return curve is used in one … Ver más It shows a steep relationship at relatively low filling pressures and a plateau, where further stretch is not possible and so increases in pressure have little effect on output.
