The treadmill ECG stress test (TMT) is part of health check packages recommended for asymptomatic people to detect diseases at an early age that can prevent or reduce future morbidity and mortality. The TMT test has an average sensitivity of 68% and a specificity of 77%. In this article, learn about the TMT test for the heart, why it is done, and the normal range of TMT for people.
Heart-related complications are often life threatening, if not fatal. Rapid heart rate, shortness of breath, discomfort and pain in the chest – all of these are common signs of cardiovascular complications that you are likely taking for granted. Routine and complete screening allows you to live a carefree life without the burden of worries in your head. Get routine tests to stay updated about your heart function.

What is the need for the TMT Test for Heart?
The TMT test helps diagnose heart conditions and see how well your heart handles the workload. Your doctor might suggest you a TMT test if you are undergoing heart surgery, heart treatment, or starting some vigorous exercise program. Other reasons for which a doctor might recommend a TMT test are-
- Diagnosis of the damage or disease in the coronary arteries due to the accumulation of cholesterol or other substances (plaques).
- Diagnosis of cardiac arrhythmia that can occur due to improper coordination of the electrical impulses.
- Plan the treatment of heart disorders
- Diagnose cardiovascular health
You might also be recommended a TMT test if you have one or more of the following symptoms that indicate a heart disease:
- Fast heartbeat
- Irregular heartbeat
- Dizziness
- Chest pain
- Breathing difficulty
What is the normal range of TMT?
During a TMT test, you will be asked to exercise at approximately 85% of your maximum heart rate. The maximum heart rate is calculated by subtracting your age from 220. The TMT test can be either negative or positive. A negative TMT test indicates that the patient could reach a certain heart rate without showing any changes in the ECG result. Whereas a positive TMT result indicates that there were changes in the ECG report were obtained post-workload.
Doctors also evaluate how well your heart rate recovers post-exercise. The recovery is calculated by subtracting the heart rate one minute after exercise from the peak heart rate. The inferences drawn are tabulated below:
S.No. | Peak heart rate minus the heart rate 1 minute after intense exercise | Inference |
1. | < 12 bpm in a walking recovery | Abnormal |
2. | > 12 bpm in a walking recovery | Normal |
3. | < 18 bpm while lying on the back | abnormal |
4. | > 18 bpm while lying on the back | Normal |
During a TMT test, your blood pressure is also monitored. The changes in the diastolic and systolic blood pressure can be an indication of certain health conditions. The major inferences that can be drawn from blood pressure readings are
S.No. | Blood pressure readings | Inference |
1. | Less than 10 mm Hg increase in the blood pressure | This might be due to the blood pressure reduction medications |
2. | Less than 10 mm Hg change in the diastolic blood pressure | Peripheral vasodilation |
3. | Drop in the systolic blood pressure of more than 10 mm Hg | Severe left ventricle dysfunction or coronary artery disease |
4. | Systolic blood pressure greater than 250 mm Hg and diastolic blood pressure greater than 120 mm Hg | Severe hypertension |
Your tolerance to exercise can also be calculated through the TMT test. These values are calculated in terms of metabolic equivalents or METS. METS refers to the uptake of oxygen expressed in kg/minute. The inferences that can be drawn from the TMT test are listed below:
S.No. | METS Reading | Inference |
1. | < 5 METS | Poor |
2. | 5 - 8 METS | Fair |
3. | 9 - 11 METS | Good |
4. | > 12 METS | Any METS score above 10 indicates a 5-year survival rate of around 95%. |
What are the risks associated with the TMT test for the heart?
The treadmill test, or TMT test, is safe and risk-free. It is considered harmless when you perform it in a controlled atmosphere under the guidance of an experienced physician.
Still, there are some dangers associated with the TMT test:
- Chest Pain
- Fainting or collapsing
- Heart Attack
- Irregular heart rhythms
- A heart attack
There is a slight possibility that you will experience falls or injuries during the treadmill exercise at the time of the TMT test, mainly for those individuals who try hard to maintain balance on the treadmill or have mobility problems.

What is the procedure for the TMT test?
Give essential guidelines to the patient before the TMT test. The TMT test procedure should be performed under controlled conditions. Below are the step-by-step instructions for the TMT test procedure:
- Preparation: The patient should be given instructions, and may be asked to avoid eating or drinking coffee a few hours before the test.
- Electrode Placement: The expert places the electrodes on the patient’s chest. This is done to monitor their heart’s electrical activity via ECG.
- Baseline Measurements: Before the treadmill starts to perform the TMT test, the patient’s resting heart rate, ECG readings, and blood pressure are recorded.
- Treadmill Exercise: The patient begins to walk slowly on the treadmill. He will gradually speed up his speed, and incline at specified intervals.
- Monitoring: The three parameters, which are the patient’s ECG, blood pressure, and heart rate, are continuously monitored.
- Evaluation of symptoms: closely assessing the patient’s chest pain, shortness of breath, and fatigue.
- Stopping the TMT test: This is the termination of the TMT test. It is performed when the patient achieves the target heart rate. Also, he experiences symptoms, or if there is any damage or change to the heart muscle.
- Evaluation after the TMT test: Once the TMT test is done, it is time to monitor the patient’s recovery, and abnormal findings are discussed with the doctor for further evaluation and management.

What is the patient advised to do after a TMT test?
A patient is advised to rest briefly after the treadmill test (TMT). This helps their heart rate and blood pressure to return to normal. If you feel any discomfort or inconvenience during the TMT test then you should immediately report to your healthcare provider. The doctor will review the TMT test results, and treatment or suggestions will be discussed.
What do the results of the TMT test mean?
The TMT test looks for the patient’s abnormalities in heart rate, blood pressure, and ECG readings during exercise.
- If the TMT test result is positive, it indicates irregularities in the heart due to exercise stress. Besides, it is also suggestive of coronary artery disease or other cardiac issues.
- On the other hand, if the TMT result is negative, it indicates the patient’s normal heart function under stress. Besides, a negative TMT result also suggests a lower likelihood of cardiac issues or underlying coronary artery ischemia.
However, doctors will consider other factors, such as the patient's history and other symptoms, to interpret the test results.
A list of precautions that a patient should take before undergoing TMT:
A patient should keep a few guidelines in mind before going for the test to ensure the accuracy of the results:
- Fasting: It is advisable not to eat or drink anything, especially caffeinated drinks, for a few hours before the treadmill test. This will help get the desired results.
- Brisk Walking: He or she may be advised to walk briskly for a few days before the test.
- Medications:: Tell your doctor about any drugs or medications you take. Their interaction can cause side effects.. He may suggest stopping or continuing to take them, even for the test. Some medicines may cause side effects.
- Wear comfortable clothes: Choose comfortable attire, even footwear, to avoid discomfort during the TMT test.
- Rest: Do not indulge in rigorous activities on the TMT test day to avoid hormone fluctuations.
Note: An asthma patient should use an inhaler before the test.
Takeaway
The TMT or treadmill stress test is a safe, non-invasive and affordable screening test for the diagnosis of coronary artery diseases (CAD). It is an essential diagnostic test for people at a higher risk of developing cardiovascular diseases. Now that you know what a TMT test is, who are the best candidate for the test and what the values of the test report mean, you will be able to analyze your health status better.

If your doctor has cleared your TMT results, it’s a good sign, but persistent dizziness shouldn’t be ignored. Common causes include dehydration, low blood pressure, inner ear issues, low blood sugar, or anemia. Monitor your symptoms, stay hydrated, and eat balanced meals. If dizziness persists, consult your doctor for further evaluation.

My TMT test was negative. Operator at Diagnostic centre, did not capture and enter BP during RECOVERY STAGE. Hence in reports, BP mentioned at Stage 3 ( 150/80) and it shown same in all stages of recovery. Based on constant BP 150/80, stage 3 on words, my insurance company, declined my insurance proposal, stating that " abnormal observations during TMT. What is solution for this type of error by Diagnostic Lab
Myhealth Team

You should contact the diagnostic centre and explain the BP recording error during the recovery phase. Request a corrected report or a re-test with accurate BP measurements. If a re-test isn’t possible, ask for a letter from the centre clarifying the error. You can also have your doctor review the report and provide support for the correction when dealing with the insurance company.

Cardiac stress analysis is POSITIVE for inducible myocardial ischaemia at good work load and 98% of maximum heart. What it means?
Myhealth Team
Apr 1, 2024 at 10:01 AM.
Hi Gopal,
A positive result for inducible myocardial ischemia on a cardiac stress analysis suggests that there is evidence of inadequate blood flow to the heart during physical exertion. This can indicate potential blockages or narrowing in the coronary arteries, which supply blood to the heart muscle.
The fact that it occurred at a good workload and 98% of maximum heart rate indicates that the heart is not receiving sufficient blood flow even during periods of increased demand, such as during exercise when the heart needs more oxygen-rich blood.
This finding warrants further evaluation by a cardiologist to determine the severity of the condition and to develop an appropriate treatment plan, which may include lifestyle changes, medication, or procedures to improve blood flow to the heart. It's important to follow up with your healthcare provider for personalized guidance and management.
Thankyou

Thanks for the enquiry. Having a pain, heaviness or discomfort in your chest can be scary. It does not always mean that you are having a heart attack. There can be many other causes, including angina, Panic attacks, Digestive problems, such as heartburn or esophagus disorders Sore muscles,Lung diseases,such as pneumonia, pleurisy, or pulmonary embolism Costochondritis. Some of these problems can be serious. Get immediate medical care if you have chest pain that does not go away, crushing pain or pressure in the chest, or chest pain along with nausea, sweating, dizziness or shortness of breath. Treatment depends on the cause of the pain.
