• Allow approximately two hours for the test.
• If you taking any heart or blood pressure medications check with your doctor. He/she may ask you to stop taking it two or three days before the test.
• Bring a list of medications you routinely take.

WHAT IS A STRESS ECHOCARDIOGRAM?

A stress echocardiogram is a test that combines an ultrasound of the heart with an exercise test. The test allows your physician to learn how well your heart functions when it is made to work harder. It helps diagnose coronary artery disease or identifies areas of the heart that lack an adequate blood supply due to narrowed or blocked coronary arteries. Coronary arteries are located on the outside of the heart and bring oxygen rich blood to the heart muscle. During an echocardiogram, a small device called a transducer is held against the chest. The transducer sends ultrasound waves that reflect (echo) off the heart. The echos are converted into moving images of the heart, which are displayed on a computer screen and recorded on videotape. The exercise test is done while you walk on a treadmill or pedal a stationary bicycle. During the test, an electrocardiogram (EKG) records the electrical activity of the heart.

WHAT HAPPENS DURING THE TEST?

Several electrodes (adhesive patches) will be placed on your chest to record heart activity during exercise. You will be shown how to properly use the treadmill with support railings or a stationary bike. The treadmill will start slowly, and the speed and incline will increase gradually. The exercise portion usually lasts about 9-12 minutes. You will be instructed to report any symptoms such as chest discomfort dizziness, and shortness of breath or leg fatigue. After you have reached peak exercise the treadmill will be stopped and the echocardiogram will be performed. You will be asked to lie on your left side while the echocardiographer records sound waves and other measurements of your heart. A " contrast" suspension may be needed to improve the quality of the study. If needed this will be administered by the cardiologist with a catheter needle placed in your arm. The "Echo" will take approximately 15 minutes to complete.
