Stress Echocardiogram (Stress Echo)

What is a stress echo test?

  • A stress echo is a noninvasive test that combines two tests, a treadmill stress test and an echocardiogram.
  • 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 the 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 you walk on a treadmill, gradually increasing the speed and incline. You will exercise from a few minutes up to 15 minutes depending on your level of ability.
  • The test will be stopped if you become too tired or have any symptoms such as chest pain.
  • The cardiologist looks for changes in the ECG pattern and any symptoms that you may experience.
  • At the peak of exercise, the treadmill will be stopped, and you 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 30 to 60 minutes.
  • This test must be ordered by a doctor.

Why is a stress echocardiogram done?

This test will help the doctor evaluate cardiac conditions related to:

  • Irregular heart rhythms
  • Decreases in oxygen or blood supply to the heart at rest, as well as with exertion
  • Overall level of cardiovascular conditioning
  • How hard the heart can work before symptoms develop
  • How quickly the heart recovers after exercise
  • Structural abnormalities such as heart valve problems

What preparation is needed?

  • Have nothing to eat except water four hours prior to test
  • Do not take caffeine, and do not smoke at least four hours prior to test
  • It is important for you to ask your doctor:
    • How to adjust your insulin and food intake prior to the test if you are diabetic
    • Wheather you should take your regular medications the morning of the test
    • Wheather you should STOP any medications prior to the test and if so how long before the test should you stop your medications
    • 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.
    • Plan to arrive at least 15 minutes prior to the test.
