Average total cost, sometimes referred to as the per unit total cost, is the per unit cost. This includes fixed costs, those costs that are required for production but do not change based on output, and variable costs, those costs that increase (or decrease) as output increases (or decreases).
Stress Testing/Stress Echocardiogram A stress echocardiogram is a non-invasive test that combines two tests--a treadmill stress test (TST) and an echocardiogram (ECHO). This test is used to see how the heart muscle contracts during rest and during exercise. A stress echo is made up of three parts: a resting echo study, a stress test, and a repeat echo while the heart is beating fast.
