How is a Stress Test performed?
- A Stress Test requires the patient to run on a treadmill or pedal on a stationary bike
- During the Stress Test, a technician will put electrodes on the patient’s chest to monitor the heart; these will be attached to an ECG machine which monitors heart activity. Blood pressure readings are recorded as well
- First, the heart rate and blood pressure will be monitored at rest
- The test will gradually increase in difficulty and the patient will continue to exercise until they feel exhausted
What does the Stress Test / Treadmill Stress Test tell you and your doctor?
- The exercise capacity and the physical endurance that the heart can bear
- Any signs of heart disease or of a weakened heart
- The effectiveness of the ongoing heart-related therapy
How to prepare for a Stress Test?
Though no real preparation is necessary, it is commonly suggested that the patient should avoid a morning walk on the day of the test, have a light breakfast, and wear loose clothes and sports shoes. Male patients should shave their chest before they come in.
