Why Do We Take A TMT Test?

A cardiac stress test, is also known as a cardiac diagnostic test. This is primarily a cardiological test that is designed to measure the heart’s ability to respond to every kind of external stress in a controlled and clinical environment. The stress response is therefore induced by some exercise or even with some drug stimulation.

The definition of cardiac stress tests:

This is a kind of test that is done in order to compare the coronary circulation, while the patient is at complete rest. Along with this the same patient’s circulation during some maximum physical exertion, showing any kind of abnormal blood flow to the actual myocardium (heart muscle tissue), is measured. The results can, therefore, always be interpreted as a kind of reflection on the overall physical condition of the test patient.

The purpose of the test:

This is a kind of test that can be used to diagnose the coronary artery disease, which is moreover known as the ischemic heart disease, and for the patient prognosis after a myocardial infarction, in other words, heart attack.

The types of cardiac stress tests:

The cardiac stress test is basically done with the heart stimulation, either by exercise on a treadmill, or by pedalling a stationary exercise bicycle Ergometer. Apart from these two this test can be conducted with an intravenous pharmacological stimulation, with the patient connected to an electrocardiogram (ECG).

The main purpose is to increase the level of mechanical stress and hence recognize the activity of the heart. The level of the speed and the difficulty is progressively increased by adjusting the range of exercises. There is, however, not a single test in this genre, but some varied range of tests. They are the following:

  1. ECG – The test is most commonly called a cardiac stress test, done with a device, recognizing your heart activity.
  2. Exercise testing – This is again a kind of test, which is basically said to measure your heart’s activity.
  3. The Treadmill test or TMT Test – The next form of test, which is used for the similar purpose.
  4. The exercise tolerance test – This is done in order to check your heart issues in the most effective manner.

The TMT Test:

The Treadmill test is actually a kind of exercise stress test, which is said to be one of the most common forms of stress tests. The main purpose of this test is to induce, some myocardial ischemia for the diagnostic evaluation of the coronary artery disease. In this TMT Test, the subject or the patient is made to walk on a treadmill, as per the protocol of the same.

As to go with the series of protocols, then one of the common form in the genre is the Bruce protocol. Every stage of this consists of three minutes and hence, it is accurately done. The starting speed is always 1.7 miles per hour (mph) and the gradient is 10%.


Hence, it can be concluded that this is a special kind of test, which is basically used to measure your heart health. There are some other forms of stress test namely:

  1. The Dobutamine Stress Echocardiography
  2. The Adenosine Stress Test
