تخطيط صدى القلب بالمجهود

A stress echocardiogram is an ultrasound test of the heart performed while your heart is working harder, or “under stress.” The test helps me assess how well your heart copes with increased activity.

During the test, you may be asked to exercise on a treadmill or an exercise bike. Alternatively, I may give you medication to make your heart beat faster and stronger. The exercise starts gently and gradually becomes more challenging. I will take images of your heart either during exercise or immediately afterwards to see how it functions under stress.

Why might a stress echocardiogram be recommended?

The aim of the test is to see how your heart responds when it needs more blood. If a part of the heart is not receiving enough blood due to a narrowed or blocked artery, that area may not contract as well as the rest of the heart when under stress. This helps me identify areas of reduced blood flow and assess overall heart function.

Preparation

  • You may be asked to stop certain medications such as beta-blockers 48 hours before the test if you take them regularly.
  • You do not need to fast, but it is best to avoid a very heavy meal 2–3 hours before the test.
  • Wear comfortable clothing and walking shoes if exercise is involved.

Additional procedures

Occasionally, a contrast study may be required. This involves a harmless liquid contrast to help produce clearer images of your heart.

After the test

I will review and interpret the results carefully. Usually, you will be able to find out the results the day after the procedure. I normally contact patients directly, but if you have any concerns, you can phone my secretary for advice.
