A Stress ECG or TMT (Treadmill Test) is a type of electrocardiogram that is performed while the patient is exercising on a treadmill or stationary bike. This test is used to evaluate the heart's response to physical exertion and to detect any abnormalities in the heart's electrical activity that may not be present at rest.
During a Stress ECG, the patient's heart rate, blood pressure, and ECG are continuously monitored while they exercise on a treadmill or stationary bike. The intensity of the exercise is gradually increased, and the patient is asked to exercise until they reach a target heart rate or until they experience symptoms such as chest pain, shortness of breath, or fatigue.
The test is usually performed to diagnose coronary artery disease or to evaluate the effectiveness of a treatment plan for this condition. The test can also be used to assess the risk of heart attack or other heart-related problems during physical activity. A Stress ECG is generally considered safe and painless, although it can be physically demanding and may not be suitable for all patients.
