Treadmill Test (TMT)

The Treadmill Test (TMT), or Cardiac Stress Test, is a medical test that measures the heart’s performance under physical stress. It is commonly used to diagnose coronary artery disease (CAD), assess exercise tolerance, and evaluate symptoms like chest pain, shortness of breath, or palpitations.

🔹

How the Test Works:

• The patient walks on a treadmill at gradually increasing speeds and inclines.

• Throughout the test, the patient’s ECG (electrocardiogram), heart rate, blood pressure, and symptoms are closely monitored.

• The test continues until the target heart rate is reached, or symptoms appear (like chest discomfort, fatigue, or ECG changes).

🔹

Why TMT is Done:

• To detect narrowed or blocked heart arteries

• To uncover exercise-induced arrhythmias

• To evaluate chest pain or breathlessness

• Before or after heart surgery or angioplasty

• To assess fitness levels for strenuous physical activity

🔹

Duration & Safety:

• The test takes about 15 to 30 minutes including preparation and recovery time.

• It is generally safe and conducted under strict medical supervision.

• If the patient cannot exercise, a pharmacological stress test using medication may be done instead.

TMT is a valuable and cost-effective tool for the early detection of heart disease, helping guide timely treatment and lifestyle modifications.
