The GXT is a diagnostic test used to rule out coronary artery disease and/or abnormal rhythms and to evaluate exercise capacity.
Why you are having this procedure (symptoms/indications):
You will sign a consent form giving us permission to test you. You will be placed on a heart monitor and blood pressure machine that will record your heartbeat and blood pressure while walking on a special exercise machine (treadmill). The treadmill will speed up and incline every three minutes while you are walking. It can detect heart disease earlier by placing your heart under stress. It will record an electrocardiogram ever three minutes. A nurse will be present during the test and a doctor will be immediately available.
Prep for the procedure:
Prep for the procedure: Wear comfortable two-piece clothing and walking shoes. Take all your medications as usual. We prefer you not eat three hours prior to the test.
What to expect:
To walk the treadmill for as long as possible and to let the nurse know if you have chest pain, shortness of breath, dizziness or leg pain during or after the test.
Persons with known or undiagnosed heart disease are at increased risk to cause complications such as abnormal blood pressure, abnormal heartbeat or function, possible heart attacks or cardiac arrest.
Post procedure instructions/limitations:
When to call your cardiologist:
