Provides different information with which to assess the condition of your heart and cardiovascular system
In addition, it provides health care providers with information on your exercise heart rate, rhythm or any abnormalities — as measured by an ECG. It also enables health care providers to see if exercise reproduces any heart or lung symptoms, and how exercise affects other aspects of your cardiovascular system, such as blood pressure and blood flow. Measures your ability to exercise at varying levels
It’s predictive of cardiac outcomes, and exercise duration is strongly associated with the risk of coronary events and death. Often doesn’t require any imaging, such as a cardiac nuclear scan or ECG to be done in conjunction with the test, since the ECG tracings are often sufficiently informative
Still, imaging studies are frequently performed with an exercise stress test, when needed. Is less expensive and takes less time
In addition, the drugs given to mimic exercise or stress can have side effects of their own. If the treadmill is a barrier — perhaps because of balance issues or knee arthritis — then other forms of exercise often can be substituted. Exercise bikes are often available as alternatives to the treadmill.
