Echocardiogram/Stress Test Q & A


What is an echocardiogram?

A cardiac ultrasound exam, or echocardiogram, is a painless diagnostic test that uses sound waves to create moving pictures of your heart. Besides revealing the size and shape of your heart, these pictures also show how well your heart’s valves and chambers are working.

An echocardiogram can help Dr. Castello see areas of your heart muscle that don’t contract well. It can also be used to detect blood clots in your heart, fluid build-up, and problems with your aorta.   

An echocardiogram may be used to diagnose:

  • Abnormal heart valves
  • Abnormal heart rhythms
  • Inflammation or infection
  • Atherosclerosis
  • Coronary heart disease
  • Congestive heart failure

What happens during an echocardiogram?

To conduct an echocardiogram, the sonographer at CardioHealth places three small, flat sticky patches called electrodes at various points on your chest.

The electrodes are connected to an electrocardiograph (EKG) monitor that registers your heart’s electrical activity over the course of the exam.

After you lie down on your left side, the sonographer will place an instrument called an ultrasound transducer on various areas of your chest and abdomen.

The tip of the wand is coated with a small amount of skin-safe gel to help facilitate clearer pictures. You may be asked to change positions a few times during the exam to help the sonographer get a complete range of images covering different areas of your heart.

Aside from the slight pressure you may feel as the transducer passes over various areas, an echocardiogram is a relatively comfortable procedure.

What is a stress echocardiogram?

Some cardiovascular problems, such as coronary heart disease, are much easier to diagnose when your heart is working harder than normal, and your heart rate is elevated.

During a standard stress test, you walk on a treadmill or pedal a stationary bike to make your heart work harder.

If you have a medical condition that prevents you from exercising during a stress test, you may receive a medication that makes your heart work harder temporarily. This type of test is known as a pharmacological stress test.

A stress echocardiogram is designed to capture moving images of your heart when it’s working harder than usual. It’s one of the best ways to see how your heart’s chambers and valves function under stress, as well as whether you have any areas of weak or dead heart muscle tissue that no longer contract properly.

How do I prepare for diagnostic heart testing?

If you’re scheduled to have a standard echocardiogram without a stress test, you may be able to eat and drink as you usually would in the hours leading up to your appointment.

If you’re scheduled to undergo a stress echocardiogram, however, you may need to avoid caffeine for 24 hours and fast for a short time before your appointment. Dr. Castello and his team will give you a complete list of pre-exam instructions to help ensure accurate results.
