In the absence of any influences the SAN pacing rate would be 100 bpm, however heart rate and cardiac output must be able to vary in response to the needs of the body. Download figure Download PowerPoint. Cardiac physiology or heart function is the study of healthy, unimpaired function of the heart: involving blood flow; myocardium structure; the electrical conduction system of the heart; the cardiac cycle and cardiac output and how these interact and depend on one another.
