Exercise test in Turkey: what it is and how it works
An exercise test, also called an exercise ECG, treadmill test, stress test or ergometry, records the heart's electrical activity, heart rate and blood pressure while you walk on a treadmill or pedal a bicycle against rising resistance. A healthy coronary artery widens to carry more blood as effort increases. If an artery is narrowed, the heart muscle behind it may not get enough blood at higher workloads, and this can show as chest discomfort, breathlessness, a blood-pressure response that is not normal, an abnormal rhythm or typical changes on the ECG trace. Cardiology departments in Turkey perform the test in an outpatient setting, usually as one part of a wider cardiac check-up.
This guide explains what the test shows, how it is done, how accurate it is, what it costs compared with the UK, US and Germany and what to ask before you book. Related services are listed in our overview of cardiology treatments in Turkey.
When is an exercise test recommended?
Doctors use an exercise test for several reasons. The most common is to assess chest pain or breathlessness on effort that might come from coronary artery disease. It is also used to check exercise capacity and blood pressure in people with known heart disease, to look for rhythm problems that appear only with exercise, to see how well treatment is working after a stent or bypass, and to assess fitness before starting a sports programme in people with several heart risk factors. In people with a heart valve condition, a supervised test can reveal symptoms that were not obvious in daily life, as in some cases of aortic valve disease.
It is not a general screening test for healthy people with no symptoms and a low risk, and the NHS and cardiology societies do not recommend it for that purpose.
What happens during an exercise test, step by step?
A technician places 10 or so electrodes on your chest after cleaning, and sometimes shaving, small areas of skin. A resting ECG and blood pressure are recorded. In the commonest protocol (the Bruce protocol) the treadmill speed and slope increase every three minutes, so the workload rises gradually. The cardiologist or a trained nurse watches the ECG, heart rate and blood pressure throughout and asks how you feel. Most people exercise for 6 to 12 minutes, and the whole appointment lasts 30 to 60 minutes. The test is stopped when you reach the target heart rate, usually about 85% of the age-predicted maximum, or earlier if you have symptoms, abnormal ECG changes or a high blood-pressure reading. Your heart rate and ECG are then watched for several minutes of recovery.
If you cannot walk on a treadmill because of knee, hip or lung problems, the cardiologist may use a bicycle ergometer or switch to a drug (pharmacological) stress test.
How accurate is an exercise test, and what can it miss?
An exercise ECG is a useful and widely available first test, but it is not perfect. It can show signs that blood flow to the heart muscle is reduced at higher workloads, and the exercise capacity it records is a strong predictor of long-term outcome. Its limits are that a normal result does not rule out all coronary disease and an abnormal result is not proof of a blocked artery. False positives are more common in women, in people with an abnormal resting ECG and in those taking some drugs, and false negatives occur when narrowings are mild or the effort is too low. For this reason the result is always read together with your symptoms, risk factors and, where needed, an imaging test.
Exercise test or stress echo, nuclear scan and coronary angiography?
When the exercise ECG is unclear, or the resting ECG is already abnormal, the cardiologist may add imaging to the stress. The choice depends on the question being asked, your body and local equipment. Our page on echocardiography explains the ultrasound used in stress echo, and coronary angiography is the invasive test that shows the arteries directly.
| Test | Best suited to | Typical limits |
|---|---|---|
| Exercise ECG (treadmill) | First assessment of effort symptoms; fitness and blood pressure response | Moderate accuracy; needs a normal resting ECG and good exercise ability |
| Stress echocardiography | Unclear ECG, women, valve or wall-motion questions | Depends on image quality and operator skill |
| Nuclear (perfusion) stress scan | Patients who cannot exercise or need a map of blood flow | Uses a small radiation dose; costlier |
| Coronary angiography | Confirming and treating blockages | Invasive; small risk; not a first-line test |
Exercise test cost in Turkey compared with the UK, US and Germany
The figures below are approximate ranges for a stress ECG on its own, not hospital quotes. Adding echocardiography or a nuclear scan raises the price considerably. The exercise test price depends on the type of test, the equipment, the consultant's time and whether a consultation and report are included. Each hospital confirms its exercise test cost in writing.
| Country | Approximate cost range |
|---|---|
| Turkey | €40 – €300 |
| United Kingdom | €150 – €700 |
| United States | €300 – €1,800 |
| Germany | €100 – €500 |
In Turkey the test is often priced inside a cardiac check-up package with a consultation, resting ECG, blood tests and echocardiography. Compare what each package contains and whether the cardiologist's report in English is included.
How do I prepare for an exercise test?
Wear loose clothing and comfortable, flat shoes, and avoid a heavy meal, caffeine and smoking for two to three hours before the test unless the hospital advises otherwise. Bring your medication list. Some drugs, notably beta-blockers, change the heart-rate response, and the cardiologist will tell you whether to take or hold them; do not stop heart medication by yourself. Bring earlier ECGs, echo reports and discharge letters, because they allow a proper comparison. If you have chest pain at rest, new breathlessness or palpitations, tell the staff before starting.
Who should not have an exercise test?
The test is postponed or replaced when the risk outweighs the benefit. Reasons include a recent heart attack, unstable angina, uncontrolled irregular heartbeat, severe symptomatic aortic stenosis, uncontrolled heart failure, acute inflammation of the heart or lungs, a blood clot in the lung or leg, very high blood pressure at rest and an acute illness with fever. The cardiologist checks your history and resting ECG first. Leg pain on walking can also come from poor circulation or veins rather than the heart; vein problems are discussed under sclerotherapy of varicose veins.
What happens after the exercise test, and is there any recovery?
Exercise test recovery is short. You rest until your heart rate and blood pressure return to normal, usually 5 to 15 minutes, and then you can drink, eat and go back to normal activity. You may feel tired or slightly dizzy for a short time, and the electrode sites can itch. The cardiologist reviews the tracing and gives the result the same day, together with advice about further tests, medication or lifestyle. Because the test takes under an hour, it can be placed in a single day of a wider check-up, and most visitors stay one to three nights in Turkey when combining it with other tests.
What are the risks of an exercise test?
An exercise test is considered safe when it is supervised by trained staff with a defibrillator and emergency drugs available. Common effects are tiredness, breathlessness, muscle aches and skin irritation from the electrodes. Serious events such as a dangerous rhythm, heart attack or collapse are rare, but they are the reason the test must be done in a unit with resuscitation equipment and why you should report symptoms at once. Professional bodies such as the European Society of Cardiology and the American Heart Association publish guidance on indications and safety.
How to choose a cardiology centre, and red flags
Choose a licensed hospital where a cardiologist, not only a technician, supervises and reports the test, where a defibrillator and an emergency team are on site and where echocardiography and angiography are available if the result needs follow-up. Red flags include a result handed over with no explanation, a diagnosis of "heart disease" from a stress ECG alone, pressure to book an angiogram without a clear reason, no report you can show your own doctor and no named cardiologist.

Frequently asked questions
An exercise test records the heart's ECG, heart rate and blood pressure while you walk on a treadmill or pedal a bicycle with rising effort. It helps show whether the heart muscle gets enough blood when it works harder.
The whole appointment takes 30 to 60 minutes. The exercise itself usually lasts 6 to 12 minutes, followed by several minutes of rest while the heart rate and blood pressure are monitored.
Approximate ranges are €40 to €300 in Turkey, against about €150 to €700 in the UK. Prices rise if echocardiography or a nuclear scan is added; the hospital confirms its price in writing.
It is a useful first test but not perfect. A normal result does not rule out all coronary disease, and an abnormal one does not prove a blocked artery, so the result is read with your symptoms and risk factors.
It is considered safe when supervised by trained staff with emergency equipment available. Serious events are rare, and you should stop and report chest pain, dizziness or severe breathlessness immediately.
The test is not painful. You may feel tired, breathless or have mild chest discomfort if the heart is short of blood, and the electrode stickers can irritate the skin.
A standard stress test records the ECG only. A stress echo adds heart ultrasound before and after exercise to look at how the walls move, which helps when the ECG is hard to interpret.
Follow the cardiologist's instructions. Some drugs, especially beta-blockers, change the heart-rate response and may be held, but you should never stop heart medication on your own.
The cardiologist usually advises further tests such as stress imaging, CT or coronary angiography, and may adjust medication. An abnormal test is a reason for further assessment, not a diagnosis by itself.
The test needs one visit and a few hours. Most visitors stay one to three nights when combining it with a cardiac check-up, so that blood tests, echocardiography and the results consultation fit in.
