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.
I often will explain to middle aged patients that no, they don't need a stress test. A basic exercise EKG costs about $200. Some doctors use a nuclear stress test in which a radioactive dye illuminates how well the heart is working. Those tests are priced at an average of $630. According to the American College of Cardiology, stress tests should only be performed on patients who have peripheral artery disease, diabetics over age 40 and people who have an increased risk of coronary artery disease.
