Resting Echo

   1. Purpose of Test

An echocardiogram examines the heart with the use of ultrasound, an imaging modality that visualizes internal structures by recording the pulsating "echoes" of harmless and painless sound waves that are directed to the heart. These high frequency sound waves are transmitted through a transducer which is a device that converts them into electrical impulses.

An echocardiograph machine converts the electrical impulses into images that are displayed onto a monitor and recorded so that a cardiologist can view them and interpret the results.

   2. What to expect during procedure

You will be asked to remove clothing from the waist up (women will be given a short gown to wear). Several electrodes will be placed on your chest to obtain an electrocardiogram and monitor your heart. You then lie down on a special bed or exam table. To improve the quality of the pictures, a technologist applies a colorless gel to the area where the transducer will be placed. The technologist places the transducer on your chest and uses a small amount of pressure to obtain the desired images. You may be asked to breathe slowly or hold your breath. The images are displayed on the screen and recorded on video. They will be compared to images taken right after exercise.

   3. How to prepare for test

Generally, you’ll be told not to eat or drink for at least 3 hours before the test. If you have diabetes and take medication for it you’ll need special instructions. If you take medication, check with your doctor when you schedule the test. He or she may ask you to stop certain medications a day or two before the test.

   4. When results will be available

The doctor conducting the test may be able to give you preliminary test results before you leave. Your own doctor will discuss the final test results with you during a future office visit.
