Exercise (treadmill) ECG

An exercise ECG, or stress test, determines whether you might have blockages in the arteries (known as ischaemia).


This controlled procedure allows us to determine how your heart performs under stress.


You will walk at a gradually increasing speed and incline on a treadmill while connected by leads to an ECG machine that measures and records the electricity traveling through your heart in real time. Your pulse and blood pressure will also be checked several times. Excess chest hair may need to be removed to allow the leads to be firmly attached.  Please let the technician know if you have any orthopedic or other limitations which may make it difficult or impossible for you to perform the test.

The ECG tracings will be examined during and after the test by the technician and later by a physician. An estimate will be made your functional aerobic capacity and maximum heart rate, which are helpful in recommending the heart rate at which you should exercise for maximum cardiac benefit. If the test is abnormal, your physician will recommend additional testing. This may include an exercise or pharmacologic echocardiogram, a sestamibi (MIBI) myocardial perfusion scan, a CT angiogram, and/or  a cardiology consultation. Additional examinations or treatment may follow.

If you have any questions please let us know at any point and we will help you find the answer you need.
