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.
A standard echocardiogram can cost $1,000 to $2,000, and a TEE can cost $2,000 or more, according to costhelper.com. If you do not have health insurance, you may have to pay the whole cost yourself. And even if you have insurance, you usually have a co-pay. This can be as much as half the cost of the test.
