Exercise Treadmill Test
Purposes of the investigation:
  • Assess for heart disease, especially for diagnosing coronary heart disease
  • Physical evaluation for patients with heart disease

Exercise treadmill is an investigation to assess how your heart, lungs and blood vessels respond to increasing workload and exercise. It is currently most frequently used to estimate prognosis and determine functional capacity, to assess the probability and extent of coronary disease, and to assess the effect of therapy.

This investigation involves walking on a treadmill while monitoring the electrical activities of your heart. Throughout the test, the speed and incline of the treadmill increase. The results show how well your heart responds to the stress of different levels of exercise.

Suitable candidate:
  • It is suitable for everyone, unless the patient is having mobility impairment.
  • Patients with chest pain during exercise, syncope or loss of consciousness.
The Procedure:
  • When the test starts, you will be walking on the treadmill at a slow speed. Every 2 to 3 minutes you will have to walk faster and more uphill. The treadmill will stop if your heartbeat reaches a certain rate, if you become very short of breath, having chest pain or if the doctor sees a problem with the rhythm of your heart.
  • Your doctor and nurse will closely monitor your ECG and blood pressure during the investigation.
  • After you have walked on the treadmill, you will be monitored for 15 to 20 minutes. You need to stay in the test area before your blood pressure and the heart rate return to normal level.
Risks and Benifits:

There are some rare risks, such as chest pain, collapsing, fainting, heart attack, irregular heartbeat. However, your risk of experiencing these reactions during the test is low, since your doctor will assess you before the test. People risked of these complications such as those with advanced coronary heart disease are rarely asked to do the test.

Treadmill is generally considered safe, especially since it is done in a controlled environment under the supervision of a trained medical professional.
