Treadmill Test

What is a treadmill test?

A treadmill test is a functional cardiac examination that assesses how the heart works during physical exercise. The test is performed while the patient walks on a moving treadmill, with continuous monitoring of the electrocardiogram, heart rate, blood pressure, and overall well-being.

This examination is used to assess impaired blood supply to the heart muscle, exercise-induced rhythm changes, and the body’s response to physical exertion.

What does the test show?

A treadmill test helps assess how the heart responds to gradually increasing physical activity. It may reveal signs of myocardial ischemia, exercise-induced arrhythmias, reduced exercise tolerance, as well as abnormal changes in blood pressure.

The test is often used in cases of chest pain, suspected coronary artery disease, heart rhythm disorders, and for evaluating the effectiveness of prescribed treatment.

Indications for the test

A treadmill test may be prescribed in the following cases:

• suspected ischemic heart disease;
• chest pain or discomfort during physical exertion;
• unexplained shortness of breath or rapid fatigue;
• heart rhythm disturbances associated with physical activity;
• hypertensive response during physical exertion;
• monitoring the effectiveness of treatment for cardiovascular diseases;
• preventive assessment before sports activities or in individuals with high levels of physical activity.

How is a treadmill test performed?

The patient then stands on the treadmill, ECG electrodes are attached, and the exercise phase begins. The level of exertion is gradually increased, while the doctor continuously monitors cardiac parameters and the patient’s well-being.

The test is stopped:

• when the predefined level of exertion is reached;
• if the patient develops symptoms;
• if potentially dangerous changes occur on the ECG or in blood pressure readings.

A treadmill test is safe and is performed under strictly controlled conditions.

How should you prepare for the test?

Before a treadmill test, it is usually recommended to:

• avoid heavy meals 2–3 hours before the test;
• avoid large amounts of coffee, energy drinks, or alcohol;
• wear comfortable clothing and shoes;
• inform the doctor in advance about any medications you are taking;
• bring previous ECGs, medical reports, or a cardiologist’s referral, if available.

In some cases, the doctor may recommend temporarily changing the schedule of certain medications, but this should only be done according to medical instructions.

Contraindications

A treadmill test is not performed or may be performed with limitations in certain conditions, including:

• early stage of acute myocardial infarction;
• unstable angina;
• severe arrhythmias;
• uncontrolled arterial hypertension;
• acute heart failure;
• severe aortic stenosis;
• acute myocarditis, pericarditis, or endocarditis;
• severe general condition or acute infectious diseases.

The appropriateness of the test is determined by the doctor in each individual case, taking into account the patient’s clinical condition and comorbidities.

Equipment

During a treadmill test, a treadmill, continuous ECG monitoring system, blood pressure monitoring equipment, and functional cardiac diagnostic software are used. This equipment allows changes in heart function to be recorded during the test and helps assess the body’s response to exercise.

Where can you undergo the test in Yerevan?

A treadmill test can be performed at Nairi Medical Center in Yerevan. The examination is carried out as part of functional cardiac diagnostics, using appropriate equipment and under medical supervision.
