Stress Echocardiograms
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 patient walks on a treadmill, gradually increasing the
speed and incline. He or she 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.
