Understanding the Difference: Echocardiogram vs. Stress Echocardiogram

#echocardiogram #stress-echocardiogram

Hello to our Buena Park Heart Center community! Today, we're going to demystify a common question we encounter in our practice: What’s the difference between an echocardiogram and a stress echocardiogram? Both are diagnostic tools we use to provide the best care for our patients, but they serve slightly different purposes. Let’s explore them.

What is an Echocardiogram?

An echocardiogram, often simply called an "echo," is a type of ultrasound test that uses high-pitched sound waves sent through a transducer (a device that collects the echoes of the sound waves) to produce images of the heart's size, structure, and motion.


  • Non-invasive: No incisions or injections are needed.

  • Detailed Imaging: Provides a clear picture of the heart's chambers, valves, walls, and blood vessels.

  • Versatile: Helps diagnose a variety of heart conditions, such as valve issues, congenital heart defects, and heart muscle diseases.

What is a Stress Echocardiogram?

A stress echocardiogram, sometimes called a "stress echo," is a two-part test. The first set of images is taken at rest, then the patient undergoes physical stress (usually through exercise on a treadmill or a stationary bike). Once the heart rate reaches a certain level, the exercise stops, and the second set of images is taken immediately. For those unable to exercise, medication might be administered to mimic the effects of exercise on the heart.


  • Dynamic Insight: Shows how the heart handles stress, which can be indicative of coronary artery disease.

  • Determines Limitations: Identifies the safe levels of exercise for patients.

  • Pinpoints Issues: Helps determine the cause of unexplained chest pain or dyspnea (shortness of breath).

Key Differences

  • Purpose: While both are diagnostic tools for the heart, a standard echocardiogram looks at the heart's structure and function at rest. In contrast, a stress echocardiogram evaluates heart function during physical stress.

  • Procedure: A regular echocardiogram only involves imaging, whereas a stress echocardiogram combines imaging with exercise or medication-induced stress.

  • Duration: Typically, an echocardiogram is quicker as it doesn't require the additional stress-testing phase.
