CARDIAC STRESS TEST or TREADMILL TEST (TMT) is a test used in Medicine and Cardiology to measure the Heart’s ability to respond to external Stress in a controlled clinical environment.
The cardiac stress test is done with heart stimulation, either by exercise on a treadmill, pedalling a stationary exercise bicycle ergometer or with intravenous pharmacological stimulation, with the patient connected to an Electrocardiogram (or ECG).
The level of mechanical stress is progressively increased by adjusting the difficulty (steepness of the slope) and speed. The test administrator or attending physician examines the symptoms and blood pressure response. With use of ECG, the test is most commonly called a cardiac stress test, but is known by other names, such as exercise testing, stress testing treadmills, exercise tolerance test, stress test or stress test ECG.
