Yes, you generally have to undress to the waist for a stress test so that electrodes can be properly placed on your chest for continuous monitoring.
We recommend you wear a loose, 2-piece outfit. Please refrain from applying lotion or powder to your chest on test day. For women, refrain from wearing an under wire bra on the day of your test. Wear shoes suitable for exercise on a treadmill.
Women—Jogging bras may be worn during nuclear and regular treadmill testing, but NO underwire bras will be allowed. Stress echo testing will mean that you will not wear a bra of any type.
How Long Will I Have to Walk on the Treadmill? The average walking time is six to nine minutes though the test may be stopped if you develop abnormal ECG changes, if you are too tired to continue, if you develop significant symptoms or if you have reached your peak heart rate.
No body lotions or creams on your chest; deodorant is OK.
The ECG technician will ask you to undress to your waist and then take a seat on the chair. They will put sticky ECG electrodes on your chest. Females may need to adjust or remove their bra and males may need a little hair removed to allow the stickers to stick.
During the test you will be constantly monitored by a nurse practitioner or a physician. The actual stress portion of the test takes about 10 to 15 minutes, however the preparation takes longer (up to 30 minutes). Before the end of the stress test, a second injection (Cardiolite) will be administered.
For an exercise stress test, you will be asked to walk on a treadmill or ride a stationary bike. You will start slowly, and the exercise gets more difficult as the test progresses. You can use the railing on the treadmill for balance. Don't hang on tightly, as this may skew the results.
A stress test is generally highly accurate for spotting blocked arteries. Adding imaging tests, like nuclear imaging or an echocardiogram, makes them more reliable. However, without these extra images, stress tests might miss smaller blockages or issues.
You may be asked not to eat, drink or smoke for a time before a nuclear stress test. You may need to avoid caffeine the day before and the day of the test. Ask your healthcare team if you need to stop taking any medicines before the test. Some medicines can interfere with some test results.
For male patients, it will be necessary to shave any area where there is hair in order to get appropriate tracings. If you prefer, you may do this at home within at least 24 hours prior to your test.
Because breast size or shape can complicate anatomical reference points, it's recommended that ECG professionals continue to place electrodes beneath the breast when necessary, though research to determine what impact alternative placement may have on ECG recordings is ongoing.
Most people don't feel pain during a stress test, though. Our goal is to help you avoid pain by having a healthy heart! If you do feel pain, let the person conducting the test know right away. Do you have questions about getting a stress test?
A stress test usually involves walking on a treadmill or riding a stationary bike. A healthcare professional watches your heartbeat, blood pressure and breathing during the test. People who can't exercise may be given a medicine that affects the heart like exercise does.
A stress echo is a more dynamic test that examines the heart in action. It combines an ultrasound of the heart with a stress test. A stress test, often called a treadmill test, measures how your heart works when experiencing added workload or “stress” of exercise. A stress echo test has 3 phases.
Do not hold on too tightly because it may affect results. You will be asked to continue exercising until your heart rate has reached a certain threshold or until you have developed symptoms like chest pain, shortness of breath, dizziness/fatigue, or an abnormal heart rhythm.
You may be asked to stop certain medications a day or two before the test. This can help get more accurate test results. Wear loose, comfortable clothing that is suitable for exercise. Men usually don't wear a shirt during the test, and women generally wear a bra and a lightweight blouse or a hospital gown.
Other signs you may have atherosclerosis (blocked arteries)
It is normal to feel nervous before a medical procedure, but stress and anxiety can influence your heart rate and test results.
TEE uses sound waves (ultrasound) to make detailed pictures of your heart and the arteries that lead to and from it. The echo transducer that produces the sound waves for TEE is attached to a thin tube that passes through your mouth, down your throat and into your esophagus.
The test ends after maintaining your target heart rate long enough to capture readings about heart function, usually about 10 to 15 minutes. Your target heart rate is higher than when at rest and based on your age and fitness level.
On test day, dress for light exercise; comfortable clothes and walking shoes are ideal. Women should wear a sports bra for comfort. Avoid caffeine on test day as it affects your heart rate and can skew results. Don't eat heavy meals within two hours of your appointment, though a light snack is fine.
The average time on a treadmill for a stress test varies by age, but most people last between 6–12 minutes. Younger, healthier individuals tend to exercise longer, while older adults or those with heart conditions may stop sooner. The test is safe and helps doctors understand your heart's health.
Results are available within 24 hours of the test.
Your maximum heart rate is about 220 minus your age. In the age category closest to yours, read across to find your target heart rates. Target heart rate during moderate-intensity activities is about 50-70% of maximum heart rate. During vigorous physical activity, it's about 70-85% of maximum.
