What Does a TMT Test Show?
A TMT test involves walking on a treadmill while monitoring the electrical activity of your heart. Throughout the test, the speed and incline of the treadmill gradually increase.
Your ECG, heart rate and blood pressure are monitored to understand how well your heart responds to the stress of different levels of exercise.
What Is a Normal TMT Test?
Your target heart rate during a stress test depends on your age. A commonly used estimate of maximum predicted heart rate is 220 minus your age. However, the appropriate target depends on your health, symptoms and doctor's assessment.
What Does the Test Evaluate?
- Heart rate response during exercise.
- Blood pressure response to physical activity.
- Electrical activity of the heart through ECG.
- Possible signs of reduced blood supply to the heart.
- Exercise tolerance and functional capacity.
What Is an Exercise Stress Test?
An exercise stress test evaluates how your heart performs when it works harder during physical activity.
Before the Test
ECG electrodes are attached to your chest. Your resting heart rate and blood pressure are checked before exercise.
Walking on the Treadmill
You will walk on a treadmill. Its speed and incline gradually increase according to the exercise protocol.
Heart Monitoring
Your heart's electrical activity, heart rate and blood pressure are monitored throughout the exercise.
Recovery & Results

Why Do Doctors Recommend an Exercise Stress Test?
A TMT test helps doctors understand how the heart responds when it needs to work harder during exercise.
Evaluate Chest Pain
It may be recommended for people experiencing chest pain or other symptoms that could be related to coronary heart disease.
Assess Blood Flow
It helps evaluate possible signs that the heart muscle may not be receiving enough blood during physical activity.
Evaluate Exercise Capacity
It helps assess your fitness and exercise tolerance, particularly when planning a new exercise programme.
Assess Heart Response
It helps your doctor understand how your heart rate, blood pressure and ECG change during exercise.
Who Should Discuss TMT With a Doctor?
People experiencing chest discomfort, breathlessness during activity or other possible symptoms of heart disease should consult a cardiologist. People with cardiovascular risk factors may also need an individual assessment to determine whether an exercise stress test is appropriate.
