TMT

"TMT" stands for Treadmill Test, also known as Exercise Stress Test or Stress ECG. It's a diagnostic test used to evaluate the heart's response to physical stress, typically exercise, and to detect any abnormalities in heart function or blood flow.

During a TMT, the patient walks or runs on a treadmill while their heart rate, blood pressure, and electrocardiogram (ECG) are monitored. The treadmill speed and incline gradually increase, causing the heart to work harder and beat faster, simulating the effects of physical exertion.

The primary purpose of a TMT is to assess the presence of coronary artery disease (CAD), which occurs when the arteries that supply blood to the heart become narrowed or blocked due to plaque buildup. CAD can cause symptoms such as chest pain (angina) or shortness of breath during physical activity.

During the test, changes in the ECG pattern, blood pressure, and symptoms such as chest pain or discomfort are closely monitored. Abnormalities observed during the test, such as ST-segment depression on the ECG, may indicate reduced blood flow to the heart muscle, suggestive of CAD.

TMTs are commonly used in the evaluation of patients with symptoms suggestive of CAD, such as chest pain or shortness of breath, and in assessing exercise capacity and overall cardiovascular fitness. They can also help determine the effectiveness of treatments for CAD, monitor the progression of heart disease, and guide decisions regarding further diagnostic testing or treatment.

TMTs are generally safe when performed under the supervision of trained healthcare professionals. However, they may not be suitable for everyone, and the decision to undergo the test is based on individual medical history, symptoms, and risk factors.
