What is a Stress Echo Test?
- A Stress Echo is a non-invasive test that combines two
tests, a treadmill stress test (TST) and an echocardiogram (ECHO).
- An echocardiogram is done at rest prior to exercise and
again at peak heart rate.
- The echocardiogram uses sound waves (ultrasound) to
provide an image of his heart's internal structures, size and movement. This image is
produced by moving a transducer (a very sensitive wand-like device) over the chest area.
- Electrodes are placed on the chest to monitor the
heart's rate and rhythm throughout the test.
- The cardiologist will have the patient walk on a
treadmill, gradually increasing the speed and incline. The patient will exercise from a
few up to 15 minutes depending upon his level of ability.
- The test will be stopped if the patient becomes too
tired, has any symptoms such as chest pain.
- The cardiologist will be looking for changes in the EKG
pattern and any symptoms that the patient may experience.
- At the peak of exercise, the treadmill will be stopped,
and the patient will be instructed to lie down immediately on a bed so that a second
echocardiogram can be taken to visualize the heart's motion with exercise.
- The test takes from 30-60 minutes.
- This test must be ordered by a doctor.
Why is a Stress Echocardiogram Done?
- This test will help doctor to evaluate the patient's
cardiac condition related to:
- Irregular heart rhythms
- If there is a decreased supply of blood and oxygen to
the heart at rest as well as with exertion
- Overall level of cardiovascular conditioning
- How hard his heart can work before symptoms develop
- How quickly the heart recovers after exercise
What Preparation is Needed?
- Nothing to eat except water four hours prior to test
- No caffeine or smoking at least 4 hours prior to test.
- It is important for the patient to ask his doctor:
- how to adjust his insulin and food intake prior to the
test if he is a diabetic.
- if he should take his regular medications the morning
of the test.
- if he is on a Beta Blocker, can he STOP taking this
medication 72 hours before the test as this is recommended for best results,.
- Do not apply lotions, oils or powders to the chest
area.
- Wear comfortable clothing (shorts or pants with shirt
or blouse) and walking or jogging shoes.
