The resting cardiac rate or pulse rate, measured in beats per minute, is maintained in a state of dynamic constancy by negative feedback loops initiated by sensors in response to changes in blood pressure and other factors.herefore, the resting pulse rate is not absolutely constant but instead varies about a set-point value. This exercise will demonstrate that your pulse rate is in a state of dynamic constancy (implying negative feedback controls).
