The exercise stress test — also called a stress ECG — is a test used to provide information about how someone’s heart responds to exertion. It usually involves walking on a treadmill or pedaling a stationary bike at increasing levels of difficulty, while your electrocardiogram, heart rate, and blood pressure are monitored.
Stress testing may help uncover heart problems that may not be evident while the body is at rest.
Doctors use the stress test to determine if there is adequate blood flow to your heart during increasing levels of activity. Stress tests are also given to evaluate the effectiveness of your heart medications to control angina and ischemia and/or to determine the likelihood of having coronary heart disease and the need for further evaluation.
