An exercise stress test records your ECG, blood pressure and symptoms while you walk on a treadmill that gets faster and steeper every 3 minutes, most often following the Bruce protocol.
It shows how your heart copes with effort and gives a useful measure of fitness. It is less accurate than imaging tests for detecting narrowed coronary arteries, particularly in women and in people with an abnormal resting ECG.
What Exercise Stress Test (Treadmill ECG) shows
The doctor watches for ST segment changes that suggest the heart muscle is short of blood, rhythm disturbances brought on by effort, the rise and recovery of heart rate and blood pressure, and the workload you reach, expressed in metabolic equivalents (METs). Chest pain that comes on at a low workload with clear ECG change points towards significant coronary disease. Good exercise capacity with no changes is reassuring and is a strong predictor of a good outlook.
When Exercise Stress Test (Treadmill ECG) is recommended
- Chest discomfort or breathlessness on effort with an intermediate likelihood of coronary disease
- Palpitations or dizziness that occur with exercise
- Checking exercise capacity before cardiac rehabilitation or a return to sport
- Assessing blood pressure response or certain rhythm problems
- Follow-up in some people with known coronary disease
Limits and situations where another test is better:
- Unstable or worsening chest pain needs urgent assessment, not a treadmill
- People who cannot walk briskly need a drug stress echo or nuclear scan instead
- Left bundle branch block, a paced rhythm or digoxin make the ECG unreadable
- Severe aortic stenosis and uncontrolled blood pressure are reasons not to test
- CT coronary angiography is often preferred as a first test when the question is whether plaque is present
How to prepare
- Wear trainers and comfortable clothes
- Avoid a heavy meal, caffeine and smoking for 3 hours beforehand
- Ask whether to hold beta blockers on the day
- Bring a list of your medicines
What happens during the test
Electrodes are stuck to your chest and a cuff is placed on your arm. You start at a slow walk and the belt speeds up and tilts in stages. You continue until you reach a target heart rate, develop symptoms or become too tired, usually after 6 to 12 minutes. Staff monitor you throughout and for several minutes of recovery.
Results and next steps
The cardiologist can normally give you the result straight after the test. A clearly abnormal test usually leads to CT or invasive coronary angiography. An unclear result leads to a stress echo or perfusion scan.
- Test time: 30 to 45 minutes in total
- Results ready: Same day
- Back to everyday activity: None
Safety and risks
- Tired legs and breathlessness are expected
- Rhythm disturbance or a fall in blood pressure that stops the test
- A heart attack or serious arrhythmia is rare, roughly 1 in 10,000 tests, and resuscitation equipment is always at hand
Arranging Exercise Stress Test (Treadmill ECG) in Türkiye
The test takes under an hour and is normally part of a cardiac check-up rather than a reason to travel. If you have new or worsening chest pain, seek care where you are instead of planning a trip.

Frequently Asked Questions
What if I cannot manage the treadmill?
Tell the team. A bicycle test, or a stress test using medication with echo or nuclear imaging, can be used instead.
Does a normal test mean my arteries are clear?
Not exactly. It means no significant flow limitation showed at the workload you reached. Mild plaque can still be present.
Can I drive afterwards?
Yes, unless you were unwell during the test.
