Stress Test (TMT)

Your doctor may recommend an exercise stress test to:

Diagnose coronary artery disease: Your coronary arteries are the major blood vessels that supply your heart with blood, oxygen and nutrients. Coronary artery disease develops when these arteries become damaged or diseased — usually due to a buildup of deposits containing cholesterol and other substances (plaques).

Diagnose heart rhythm problems (arrhythmias): Heart arrhythmias occur when the electrical impulses that coordinate your heart rhythm don't function properly, causing your heart to beat too fast, too slowly or irregularly.

Guide treatment of heart disorders: If you've already been diagnosed with a heart condition, an exercise stress test can help your doctor find out how well the treatment is working. It may also be used to help establish the treatment plan for you by showing how much exercise your heart can handle.
