What is an exercise treadmill test?
In some cases, patients with normal resting ECGs may still experience chest pain, which could be caused by slight or moderate coronary artery disease (CAD). In this case a doctor might conduct an exercise stress test. This test treadmill - also referred to as the exercise stress test – can reveal information about how the heart responds to exertion.
What happens during a treadmill test?
As its name suggests, the treadmill test usually involves walking on a treadmill, but can also involve pedaling an exercise bike at increasing levels of difficulty, while the electrocardiogram, heart rate and blood pressure are monitored.
- During the treadmill exercise, electrodes are placed on the patient's chest as they walk on the treadmill. Any chest pain or changes in the ECG may suggest that not enough blood is reaching the heart.
