What it is:

An electrocardiogram (EKG or ECG) is a test done to check for problems with your heart’s electrical activity. As a result of this test, the heart’s electrical activity is translated into line tracings on paper.

A health professional usually does the EKG, which is then interpreted by a doctor. EKGs can be part of a physical exam or during a series of tests.

Reasons for the Procedure:

- Check a heart’s electrical activity

- Determine the cause of symptoms of heart disease, such as shortness of breath, fainting, dizziness, or rapid, irregular heartbeats (palpitations)

- Determine the cause of unexplained chest pain that that could be the result of angina, heart attack or inflammation of the sac surrounding the heart (pericarditis)

- Check to see how medicines are working and whether side effects are affecting the heart

- Evaluate if the heart chamber walls are too thick (hypertrophied)

- Determine if mechanical devices that have been implanted into the heart, such as pacemakers, are working properly and controlling a normal heartbeat.

- Check on the heart’s health when other diseases or conditions – high cholesterol, smoking, high blood pressure, diabetes or family history of heart disease - are present.


How to Prepare:

-Inform you doctor of all the nonprescription and prescription medicines you are taking. - Take off all your jewelry from your wrists, arms and neck.

- Typically, men are bare-chested during this test, while women will wear a bra, T-shirt or gown.

- Stockings should be removed.



- You will be instructed to lie down on a table or bed

- Areas on your chest, arms and legs where small metal discs (electrodes) are going to be placed will be cleaned and sometimes shaved to provide a smooth, clean surface to attach the discs.

- Electrodes are attached to the skin on each leg, arm and on your chest.

- These electrodes are hooked to a machine that traces your hear heart’s activity onto paper.

- You will be asked to breathe normally and lie still during the test. At times you may be asked to hold your breath.

- During the test, you should not talk.


What to Expect:

There is no risk or pain associated with and EKG and it is not harmful in anyway – electricity is not sent into the body.



Typically this procedure takes ten minutes



You may get a rash or redness where the electrode patches were attached to your skin. This is a mild rash that typically goes away without treatment.

Usually you can immediately resume your normal routine unless advised otherwise by your provider.
