An electrocardiogram (ECG) may be done on an outpatient basis or as part of your hospital stay. Steps may vary depending on your condition and your doctor’s practices.
-
You will be asked to remove any jewelry or other objects that may interfere with the test.
-
You will be asked to remove clothing from the waist up. The technician will ensure your privacy by covering you with a sheet or gown and exposing only the necessary skin.
-
You will lie flat on a table or bed for the test. It will be important for you to lie still and not talk during the ECG, so that you don’t alter the tracing.
-
If your chest, arms, or legs are very hairy, the technician may shave or clip small patches of hair, as needed, so that the electrodes will stick closely to the skin.
-
Electrodes will be attached to your chest, arms, and legs.
-
The lead wires will be attached to the electrodes.
-
Once the leads are attached, the technician may enter identifying information about you into the machine's computer.
-
The ECG will be started. It will take only a short time for the tracing to be completed.
-
Once the tracing is completed, the technician will disconnect the leads and remove the skin electrodes.
