A TMT (treadmill test) is an advanced preventive screening test that aids in the detection of heart disease in a patient, primarily by assessing how well the patient’s heart responds during times when it is working the hardest.

It helps in-

  • Assessing unexplained, but steady chest pain and determine if the cause is coronary artery disease
  • Assessing if there are abnormal heart rhythms
  • Evaluating the effectiveness of therapy or medication for chest pain or irregular heartbeat
  • Checking whether sufficient blood flow to your heart as you get more active
  • Checking how well your heart valves are working
  • Checking whether the arteries have re-narrowed after angioplasty, especially if there is chest pain or other symptoms
  • Detecting if symptoms such as fainting, palpitations or dizziness are related to heart disease
  • Determining the ability of the heart to withstand exercise in persons who have heart disease, have had a heart attack or heart surgery
  • Developing a safe exercise routine
  • Screening for CAD (Coronary Artery Disease) in a person with no symptoms, especially if the individual is prone to CAD


The process followed during a TMT is as follows:

  • Before the test commences, a technician performs an ECG in order to measure your heart rate and to determine your blood pressure when your body is at rest.
  • You are then connected to a hyperlink ECG machine and asked to start walking on a treadmill, the speed and inclination of which is increased gradually.
  • At regular intervals, your body’s response to the exercise is assessed and the ECG is monitored continuously for signs that might indicate that the test needs to be terminated at a particular stage
  • It is necessary for you to inform the technician in case you experience any discomfort during the course of the test.

Once the test is completed, the speed and inclination of the treadmill are gradually reduced in order to allow your body to cool down. Your heart rate and blood pressure are monitored all this time and a report is prepared.

How can I prepare for a TMT?

  • Carry your jogging shoes
  • Avoid consuming a heavy meal at least two hours before the commencement of the test.
  • Wear loose, stretchable and comfortable clothing.
