Echocardiogram
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.
A doctor must order this test.
