Cardiac Stress Testing
Cardiac Stress Testing (or exercise tolerance test) is used to help evaluate the heart and vascular system during exercise. You will be watched for signs of irregular heart beat, partially blocked arteries and heart attack risk, which may not seen while you are resting. These issues may become evident when the heart has to work harder during exercise. After baseline ECG (electrocardiogram) and vital signs (blood pressure and pulse) are completed, the patient walks on a treadmill that gradually goes faster along with increasing incline.
During exercise, the patient’s ECG, blood pressure, heart rate and condition are continuously monitored by a nurse under the direction of a specialized physician. The test continues until there are ECG changes or the patient is fatigued, has symptoms of chest pain, shortness of breath or feels lightheaded.
Family doctors must forward all referrals for stress testing to the Specialist Clinic. A consultation appointment will occur with a cardiologist or internist, during their scheduled clinic, to determine if stress testing is required. If needed, the stress test can be completed on that same day. The specialist will take multiple complex factors into account as they interpret the test results to share with the patient.
