What Is A Stress Test For
Stress affects most people in some way. Acute (sudden, short-term) stress leads to rapid changes throughout the body. Almost all body systems (the heart and blood vessels, immune system, lungs, digestive system, sensory organs, and brain) gear up to meet perceived danger. These stress responses could prove beneficial in a critical, life-or-death situation. Over time, however, repeated stressful situations put a strain on the body that may contribute to physical and psychological problems. Chronic (long-term) stress can have real health consequences and should be addressed like any other health concern. Fortunately, research is showing that lifestyle changes and stress-reduction techniques can help people learn ...Read more
ForAdvancedDisease: Promoted for detecting artery disease, but misses most disease; arteries expand, not narrow. ~75%, or more, narrowing required before stress tests, all forms, begin to detect any abnormalities. Nuclear (more expensive ; radiation) promoted as more sensitive. For all I have seen, a well done ekg exercise stress more sensitive ; accurate. I quit doing stress tests 1995; for better protection options. ...Read moreSee 1 more doctor answer

There are exercise ecg's where you exercise on treadmill and you heart rate is constantly monitored, then tere are exercise nuclear and exercise echocardiograms where you exercise and pictures of your heart are taken before and after exercise, then there ate pharmacological test which pharmacological agents r used to simulate exercise. ...Read moreSee 1 more doctor answer
Stress Test: Stress EKG: Before exercising, EKG is done to measure heart rate at rest; and blood pressure is taken. You exercise by walking on a treadmill or pedaling a stationary bicycle. The rate of exercise or degree of difficulty gradually increases. After test heart rate, blood pressure, and EKG are monitored. Stress Test is used to assess chest pain ,shortness of breath are due to heart problem. ...Read more

Normal stress but abnormal myocardial moderate inferior partial reversible perfusion. What means. How stress test normal and rest abnormal.
Abnormal stress test: A "myocardial perfusion defect with reversibility" indicates that there is something reducing the blood supply to the heart muscle (eg, atherosclerosis causing a blockage in the coronary.) The exercise EKG (stress test) can appear normal even if myocardial persuion is not. Additional testing, such as a catheter angiogram, may be needed. ...Read more

Heart test: A stress test is also known as an "exercise stress test" and it involves you running on a treadmill until we "stress" your heart to it's predicted maximal heart rate(220 minus your age).If you have heart disease we often see changes in the continuous ECG done during the run. ...Read moreSee 2 more doctor answers
Imaging: Heart Imaging tests (nuclear, ultrasound & MRI) are a non-invasive way of evaluating heart function performed in conjunction with physical activity (treadmill or bicycle) or using non physical means (using intravenous medication eg. dobutamine, lexiscan, adenosine or dipyridamole). All the above provide indirect information on blood flow, presence of scars and the strength of heart contractions ...Read more
2nd test: An inconclusive test is inconclusive because they can't say for sure that it's negative or positive. You need to have a second test, preferable using a different technique, to be certain that it's actually negative. ...Read more
Nuclear stress test: The patient walks on a treadmill or other exercise device or has a medication injected to simulate exercise, when the exercise or medicine is in progress a radioactive agent is injected which goes into the heart and can be imaged to show the blood flow into the heart muscle. The information shows if enough blood gets into the heart muscle and other information. ...Read more
See below: A sestamibi stress test is used to detect decreases in blood to the heart muscle during exercise or chemical "stress." such decreases in flow may indicate partial or complete blockage of one or more of the coronary aeries that supply blood to the heart muscle. ...Read moreSee 1 more doctor answer
Checks heart functio: Thallium is a radioactive (minimally) isotope that is used to study the pumping capability of the heart, usually after heart attack or prior to surgery in someone with cardiac disease. Sometimes it's done simply to ensure proper cardiac capability in someone with risk factors or prior heart issues. It involves mild to increasing exercise to "stress" the heart and assess function under effort! ...Read more

A stress test is a cardiac test which can include walking on a treadmill and monitoring your heart while you are walking. They can also inject you with a nuclear material and do a more comprehensive scan on your heart to check for blockage. They can also do a chemical stress test which omits the need to ...Read more
