The heart is a muscular mechanical pump with an ability to generate both flow (cardiac output) and pressure. The product of flow output and systemic arterial pressure is the rate of useful work done, or power output. Cardiac pumping capability can be defined as the cardiac power output (CPO(max)) achieved by the heart during maximal stimulation. Cardiac reserve is the increase in power output as the cardiac performance is increased from the resting to the maximally stimulated state. Recently… CONTINUE READING
