Guidelines for People with Diabetes
If you take insulin to help control your blood sugar, ask your physician what dose you
should take the day of the test. It is common for a physician to suggest taking half the
usual morning dose and eating a light meal four hours before the test.
If you take pills to help control your blood sugar, DO NOT take your medication until after
the test is complete.
DO NOT take your diabetes medication and skip a meal before the test.
If you own a glucose monitor, please check your blood sugar levels before and shortly after
the test. If you think your blood sugar is low, tell the lab personnel immediately. Plan to eat
and take your oral diabetes medication after your test is complete.
What should I wear on the day of the test?
You may wear anything you like. You will change into a hospital gown prior to starting the
test. Please do not bring valuables.
What happens during the test?
• You should arrive 30 minutes before your scheduled appointment.
• Before the test, a health care provider will explain the procedure in detail, including
possible complications or side effects. Please take this opportunity to ask any questions
you may have.
• Your echo will take place in the Echo Lab. The clinical care area is under physician
supervision.
• You will be given a hospital gown to wear and asked to remove your clothing from
the waist up. Your chest will be partially exposed to allow the cardiac sonographer to
acquire the necessary images.
• A cardiac sonographer will gently rub 10 small areas on your chest and place
special patches or electrodes on these areas. These electrodes are attached to an
electrocardiograph (ECG) monitor that displays your heart’s electrical activity.
