Understanding Treadmill Test Results: A Helpful Guide

If you have recently undergone a treadmill test and are searching for information on how to interpret the results, you have come to the right place. This brief review aims to provide a simple and easy-to-understand guide on reading treadmill test results. By the end, you will gain a better understanding of what the test results mean and their significance.

  1. What are Treadmill Test Results?
  • A treadmill test, also known as an exercise stress test, is a diagnostic tool used to evaluate heart function during physical activity.
  • The results obtained from this test provide valuable insights into cardiovascular health and help identify any underlying conditions or concerns.
  1. Interpreting Treadmill Test Results:
  • Understanding the various parameters and measurements in your treadmill test results is crucial for accurate interpretation.
  • Here are some key elements to consider:

    a) Heart Rate: The test measures your heart rate during different stages of exercise.

    b) Blood Pressure: It evaluates changes in your blood pressure as you exercise.

    c) Duration: The duration of exercise achieved before stopping can indicate your fitness level.

    d) ECG (Electrocardiogram): This graph shows your heart's electrical activity during the test

Exercise capacity is based on metabolic equivalents (MET) achieved, (one MET is defined as 3.5 mL O2 uptake/kg per min, which is the resting oxygen uptake in a sitting position). Less than 5 METS is poor, 5–8 METS is fair, 9–11 METS is good, and 12 METS or more is excellent.

How do you read treadmill results?

Patients are categorized as low-, intermediate- or high-risk. Low risk (score > 5) indicates a 5-year survival of 97%. Intermediate risk (score between 4 and -11) indicates 5-year survival of 90%. High risk (score < -11) indicates 5-year survival of 65%.

What is the normal range for a treadmill test?

What is the normal range of TMT?
S.No.METS ReadingInference
1.< 5 METSPoor
2.5 – 8 METSFair
3.9 – 11 METSGood
4.> 12 METSAny METS score above 10 indicates a 5-year survival rate of around 95%.

How do you read an exercise stress test report?

Possible results of the exercise stress test include:
  1. Normal blood flow during exercise and rest.
  2. Normal blood flow when resting but not during exercise, possibly indicating a blocked artery.
  3. Low blood flow when exercising and resting, suggesting coronary artery disease.

What is a good METs score by age?

What do the numbers mean on a stress test?

Your target heart rate during a stress test depends on your age. For adults, the maximum predicted heart rate is 220 minus your age. So, if you're 40 years old, the maximum predicted heart rate is 220 – 40 = 180.

What are bad stress test results?

Failing a stress test means you cannot reach or sustain the target heart rate during the exercise portion of the test. This may be due to physical limitations, like joint pain, breathing difficulties, or underlying heart conditions like coronary artery disease.

Frequently Asked Questions

What is the average time on a treadmill for a stress test?

They record the heart's rhythm. A health care provider checks the heartbeat while the person walks on a treadmill or pedals a stationary bike. A stress test usually takes about an hour, including the prep time and the time it takes to do the actual test. The exercise part takes only around 15 minutes.

What is a bad stress test result?

What does it mean to ''fail'' a stress test? Failing a stress test means you cannot reach or sustain the target heart rate during the exercise portion of the test. This may be due to physical limitations, like joint pain, breathing difficulties, or underlying heart conditions like coronary artery disease.

What is a positive treadmill stress test?

Positive test means patients ECG is showing changes of angina (lack of adequate blood supply to heart) after workload. It means patient is suffering from ischemic heart disease.


How do I read my stress test results?
Doctors may use different scales to report your results. Some stress test results will simply say “positive” (meaning there was something concerning about your stress test) or “negative” (meaning your stress test was normal). It's possible a doctor could declare your test nondiagnostic.
What is a good number for a stress test?
What might the results show?
under 5 METS or inability to exercise for 6 minutes or raise the heart rate to 85% of maximumpoor
5–8 METSfair
9–11 METSgood
12 METS or moreexcellent, any score above 10 METS suggests a 5-year survival rate of 95%

Treadmill test results how to read

How long does the average person last on a treadmill stress test? During a stress test: Your entire stress test, including the prep time, would take about 45 minutes to an hour. The actual test takes only around 15-20 minutes.
What is a normal abnormal stress test score? If blood is flowing well through the arteries of your heart, then your test is normal. If blood isn't flowing well, you may have a blockage in one or more of the coronary arteries of your heart.
  • Is 12 minutes on treadmill stress test good?
    • The testing protocol could be adjusted to a patient's tolerance, aiming for 6 to 12 minutes of exercise duration. There is a modified Bruce protocol for those who cannot exercise vigorously, adding two lower workload stages to the beginning of the standard Bruce protocol, both of which require less effort than stage 1.
  • What is a good METs score for a stress test by age?
    • A healthy 50-year-old man should have a capacity of at least 9.2 METs; a healthy 50-year-old woman should clock in at 8.2 METs or higher, according to a recent study on women's fitness in the New England Journal of Medicine. For men age 20, 13.5 METs; age 30, 11.4 METs; age 40, 10.3 METs.
