What is an exercise ECG or stress test?
Some heart problems only show up when the heart is working hard (or stressed). An exercise ECG is a noninvasive diagnostic test that measures the heart’s electrical activity at rest and while you exercise. It is sometimes called a stress test or a treadmill test because you usually walk or run on a treadmill. This test can detect whether the heart is getting enough blood and oxygen. It also helps to determine the level of exercise that is safe for you. Who might have an exercise ECG? The exercise ECG is usually the first noninvasive stress test given to women with risk factors or symptoms of heart disease. Because it is easy to perform, widely available, and excellent for ruling out heart problems, this test is usually used before noninvasive imaging tests such as echocardiography and nuclear stress tests. Women older than 55 and men older than 45 who don’t work out regularly but plan to start a vigorous exercise program should have an exercise ECG to determine a safe level of exercise
