Single-Averaged Electrocardiogram (SAEKG)

What is a Signal-Averaged Electrocardiogram (SAECG)?

• A SAECG is a non-invasive test that records the electrical activity of the heart.
• It is similar to a regular electrocardiogram (EKG) but uses computer processing to record lower-level signals that do not normally appear on a standard EKG.
• Electrodes are placed on the chest.
• The test takes approximately 10 to 30 minutes.
• This test must be ordered by a doctor.

Why is a SAECG Done?

• Helps to predict the likelihood of high-risk patients developing life-threatening ventricular arrhythmias.

What Preparation is Needed?

• No restrictions on food, liquid or medications prior to the test.
• Do not apply lotions, oils, or powder to the chest area.

Registration:

• Pre-register 1-3 days prior to the day the test is scheduled. This will save considerable time on the day of the test. Please call 310-517-4754 to pre-register.
• Plan to arrive 15 minutes before the scheduled time of the test.
• Enter the hospital through the main lobby.
• If pre-registered go directly to the Cardiology Department which is located in the basement.
• If not pre-registered, plan to arrive an hour before the scheduled time of the test and first check in at the information desk in the main lobby in order to register.
