Weboxygen consumption. Cardiac output is determined by heart rate and stroke volume. As is true for oxygen consumption and cardiac output, there is a linear relationship between heart rate and exercise intensity up to maximal heart rates. [At this point I encourage the students to plot cardiac output and heart rate as functions of exercise ... WebExercise is an important determinant of health but is significantly reduced in the patient with a univentricular circulation. Normal exercise physiology mandates an increase in pulmonary artery pressures which places an increased work demand on the right ventricle (RV).
