A TMT, also called a treadmill test or cardiac stress test, shows how your heart behaves when it works harder. Many patients come to us for TMT along with a 2DEcho, ECG, and blood tests, all in one visit.

What is a TMT test

In a TMT, you walk on a treadmill that gradually gets faster and steeper. While you walk, your ECG, heart rate, and blood pressure are monitored continuously. The aim is to find out whether the heart muscle gets enough blood when the demand rises. Some heart problems, such as blockages in the arteries, show up only during exercise and not on a resting ECG.

When is a TMT advised?

Your doctor may recommend it if you have:

• Chest pain or tightness, or breathlessness on exertion
• Risk factors such as diabetes, high blood pressure, high cholesterol, smoking, or a family history of heart disease
• A planned start of an exercise programme after age 40, or after heart illness
• Follow-up after a heart attack, stent, or bypass
• Palpitations that happen during exercise
• A pre-operative or executive health check-up

Who should not do a TMT?

A TMT may not be safe in some situations, for example, a recent heart attack, unstable chest pain, severe uncontrolled blood pressure, serious heart rhythm problems, severe heart failure, or a severely narrowed aortic valve. Tell the doctor about your full history. In these cases, your doctor may advise a different test, such as a stress echo or CT angiography.

How to prepare for a TMT

• Wear comfortable clothes and
  sports or walking shoes.
• Avoid a heavy meal, and avoid tea, coffee, cola, and smoking for a few hours before the test. A light meal about 2 to 3 hours before is usually fine.
• Take your medicines as advised by your doctor.
  Do not stop any heart medicine on your own.
• Some tablets, such as beta-blockers, may need to be adjusted, but only on your doctor’s advice.
• Bring previous ECG, 2D Echo and reports, and a list of your medicines.
• Men with chest hair may need small areas shaved for the ECG stickers. Women should wear a front-opening or loose top and bring a comfortable sports bra if possible.

What happens during the test

1. Small ECG stickers are placed on your chest, and a blood pressure cuff is fitted.
2. A resting ECG and BP are recorded.
3. You start walking slowly, and the speed and slope increase every few minutes(commonly the Bruce protocol).
4. The doctor and technician watch you and the ECG throughout and ask how you feel.
5. The test stops when you reach your target heart rate, feel tired, have symptoms, or if the ECG shows changes. It can be stopped at any time you wish.
6. You rest while your heart rate and BP are monitored for a few minutes.

The whole visit takes about 30 to 45 minutes, and the walking itself usually takes 6 to 12minutes.

Is a TMT safe?

A TMT is generally safe when done under medical supervision. Rarely, a person may feel chest pain, dizziness, or an abnormal heart rhythm during the test. Our team is trained to manage these situations, and emergency equipment is available.

Understanding the TMT result

• Negative TMT: no significant ECG changes at the level of exercise reached. This is reassuring but does not completely exclude a blockage.
• Positive TMT:
  ECG changes or symptoms suggest reduced blood flow to the heart. This does not mean a heart attack is certain, but it means further tests, such as 2D Echo or angiography, may be needed.
• Inconclusive TMT:
  The target heart rate was not reached, or the ECG was hard to interpret. Another test may be suggested.

Your doctor will explain your result in relation to your symptoms and risk factors. Read our detailed guide: Everything you wanted to know about a Treadmill Test (TMT).

Frequently asked questions

What is the full form of TMT in medical terms?

TMT stands for Treadmill Test. It is also called a stress test or exercise ECG.

Is a TMT painful?

No. It is similar to brisk walking, but it gets more strenuous as the test progresses.

Do I need to fast before a TMT?

Not for long. Avoid a heavy meal in the 2 to 3 hours before the test. A light meal is fine. 

Can I take my medicines on the day of the test?

Follow your doctor’s instructions. Do not stop any heart medicine without advice.

What if I cannot walk on the treadmill?

Tell the doctor in advance. Alternatives such as a pharmacologic stress test or a stress echo may be suggested.

How is a TMT different from a 2D Echo?

A TMT checks how the heart responds to exercise. A 2D Echo is an ultrasound that shows the heart’s structure and pumping. See our 2D Echo test page.
