Heart Failure and the Echocardiogram
How Should I Prepare for the Echocardiogram?
On the day of an echo, eat and drink as you normally would. Take all of your medications at the usual times, as prescribed by your doctor.
What Happens During an Echocardiogram?
During the echo, you will be given a hospital gown to wear. You will be asked to remove your clothing from the waist up. A cardiac sonographer will place three electrodes (small, flat, sticky patches) on your chest. The electrodes are attached to an electrocardiography monitor (ECG or EKG) that charts your heart's electrical activity.
The sonographer will ask you to lie on your left side on an exam table. He or she will place a wand (called a sound-wave transducer) on several areas of your chest. The wand will have a small amount of gel on the end, which will not harm your skin.
Sounds are part of the Doppler signal. You may or may not hear the sounds during the test. You may be asked to change positions several times during the exam in order for the sonographer to take pictures of different areas of your heart.
You should feel no major discomfort during the test. You may feel coolness from the gel on the transducer and a slight pressure of the transducer on your chest.
The test will take about 40 minutes. After the test, you can get dressed and go about your daily activities.
What Should I Do to Prepare for a Stress Echocardiogram?
On the day of the echo, do not eat or drink anything except water for four hours before the test.
Do not take the following heart medications on the day of your test unless your doctor tells you otherwise: Beta-blockers (for example, Tenormin, Lopressor, Toprol, or Inderal); Isosorbide dinitrate (for example, Isordil, Sorbitrate); Isosorbide mononitrate (for example, Ismo, Imdur, Monoket); Nitroglycerin (for example, Deponit, Nitrostat). Your doctor may also ask you to stop taking other heart drugs on the day of your test. If you have any questions about your medications, ask your doctor. Do not discontinue any medication without first talking with your doctor.
