When your doctor has prescribed a treadmill test, you are likely to be wondering what that really tells you about your heart–and what your results may indicate.
A treadmill test, often called a TMT (Treadmill Stress Test), is used to measure the performance of your heart when your body is being physically stressed. Rather than recording the state of your heart when the body is at rest, it determines the efficiency of your heart in relation to increases in heart rate.
Let’s walk through it in a simple, clear way so you know exactly what to expect.
What Is a Treadmill Test?
Treadmill test is a diagnostic test; it is done by walking or running on a treadmill with monitoring of the heart activity.
During the test:
- Your heart rate is tracked
- Your ECG (electrocardiogram) is documented
- Your blood pressure is measured
The treadmill gradually increments its speed and gradient, allowing the doctors to see how your heart copes with more and more exertion.
What Does a Treadmill Test Show?
A treadmill test will help you to learn more about the performance of your heart during exercise.
It helps evaluate:
✔ Blood Flow to the Heart
The harder your heart is working the more oxygen it requires. When there is a restriction in blood flow then this could be an indication in terms of underlying problems such as blocked arteries.
✔ Heart Rhythm Changes
The test is able to indicate abnormal heart rhythms which would not be visible when the body is resting.
✔ Exercise Capacity
It demonstrates the duration of time you can maintain yourself physically active without feeling fatigued, finding it hard to breathe or feeling uncomfortable.
✔ Blood Pressure Response
Your blood pressure must increase in a progressive manner during exercise. Any suspicions can also give significant leads.
What Is Considered a Normal Treadmill Test?
A normal result generally indicates that your heart is functioning well during physical activity.
Typically, a normal treadmill test includes:
- No chest pain or discomfort
- Constitutional and normal ECGs.
- Slow and proper gain in heart rate.
- Normal response of blood pressure.
- The capability of doing the test according to your age and fitness level.
To the point, your heart is working under stress but it is not displaying signs of diminished blood flow.
At Ayushman Heart and Wellness, doctors carefully review these parameters to ensure your heart health is assessed accurately.
What Is an Abnormal Treadmill Test?
When the result is abnormal it indicates that your heart is not responding optimally to physical stress.
This may include:
- Chest pain during the test
- Noticeable ECG changes
- Irregular heartbeat
- Abnormal elevation or lowering of blood pressure.
- Fatigue or impotence at an early age.
It does not necessarily mean that an abnormal outcome is a sign of a serious condition, but this is an indication that it requires further assessment.
