Treadmill test (TMT)

Treadmill Test (TMT)

A Treadmill Test (TMT), also known as a stress test, is a diagnostic procedure that monitors heart function during exercise. It helps compare blood circulation in the heart at rest and under physical stress, making it an essential test for detecting coronary artery diseases and abnormal heart rhythms.

How the Test Works

During the test, the patient walks on a treadmill while their heart’s electrical activity is continuously monitored via an Electrocardiogram (ECG). The treadmill’s speed and incline gradually increase, simulating different levels of exertion. Throughout the test, blood pressure, heart rate, and ECG readings are closely observed before, during, and after exercise.

The patient is encouraged to walk as long as possible since the accuracy of the test depends on sustained effort. Any symptoms such as chest pain, dizziness, shortness of breath, or extreme fatigue should be reported immediately. After the exercise phase, monitoring continues for 3 to 5 minutes to evaluate recovery. The results are analyzed by a cardiologist.

Why is a TMT Performed?

A TMT helps diagnose and monitor:

• Coronary Artery Disease (CAD) – Detects blockages or damage in the coronary arteries.
• Post-Angioplasty or Heart Attack Recovery – Assesses heart function after treatment.
• Exercise-Induced Arrhythmias – Identifies abnormal heart rhythms under stress.
• Effectiveness of Medications – Evaluates treatment impact on angina and ischemia.
• Functional Capacity – Determines heart efficiency under exertion.

Preparation Guidelines

• Fasting required – Avoid food and drinks (except water) for at least 4 hours before the test.
• Diabetic patients – Consult a doctor regarding insulin dosage or medication adjustments.
• Wear comfortable clothing and shoes – Proper attire ensures ease during exercise.

Advantages of TMT

TMT is a widely available, cost-effective test that helps estimate heart health, assess disease risk, and determine exercise capacity. It plays a crucial role in early detection, treatment planning, and ongoing heart disease management.
