A treadmill exercise stress test is done to see how the heart responds to the stress of exercise on a treadmill.
Stress testing gives information about how your heart works during physical stress. Some heart problems are easier to diagnose when your heart is working hard and beating fast.
During a stress test, you exercise (walk or run on a treadmill or pedal a bicycle) to make your heart work hard and beat fast. Tests are done on your heart while you exercise.
Doctors usually use stress testing to help diagnose coronary artery disease and to see how severe coronary heart disease is in people who have it.
A Treadmill test determines how a heart functions when subjected to controlled amounts of stress.
Why is a TMT performed?
TMT test is done to:
Detect abnormal heart rhythms (arrhythmias)
Diagnose the presence or absence of coronary artery disease (chest pain evaluation)
Estimate the functional capacity of the patient in order to advise what level of activity a patient can perform.
What Happens During a TMT?
Before a patient start the treadmill test, an ECG test is done to determine the heart rate at rest.
The patient is asked to stand on the treadmill machine and the treadmill is then started at a relatively slow “warm-up” speed. The treadmill speed and its slope or inclination are increased every three minutes according to a pre-programmed protocol. The patient’s blood pressure is usually recorded during the second minute of each stage. However, it may be recorded more frequently if the readings are too high or too low.
How to prepare for Treadmill Test (TMT)
Do not eat or drink for three hours prior to the procedure to avoid the likelihood of nausea.
Inform the technician or doctor if you are under any medications.
Wear comfortable (loose) clothing and shoes that are suitable for exercise.
