How to Prepare for an Echocardiogram

If you display signs and symptoms of heart problems, your doctor might recommend an echocardiogram 1. The test, which uses ultrasound technology to produce pictures of the heart to see how well it is working, is a common procedure that requires little preparation, according to 1.

Is This an Emergency?

If you are experiencing serious medical symptoms, seek emergency treatment immediately.

Follow your doctor’s instructions on when you can eat and drink before the test. There are no food or drinking restrictions for a standard electrocardiogram. However, you should not eat or drink at least three hours before a stress echocardiogram and at least six hours before a transesophageal echocardiogram 12. You can drink water up to two hours before a transesophageal echocardiogram 12.
