Electrocardiogram (EKG/ECG)
Why is
the doctor performing this test?
To evaluate
the heart's function by viewing its electrical activity.
What
is the test?
 An electrocardiogram (ECG or EKG) is a painless,
non-invasive test whereby the doctor visualizes the electrical impulses of
your heart. The technician will place a total of approximately 10 electrode
patches on the skin of your arms, legs and chest (sometimes it is necessary
to shave small areas of body hair in order to get a good reading). These
electrode patches are hooked up to an electrocardiography machine which
displays the electrical activity of your heart.
This test
can give your doctor the following information about the functioning of
your heart:
- Heart attack: EKGs show
whether you are currently having a heart attack or have had one in the
past and can help differentiate between chest pain (angina) and a
heart attack.
- Heart rate and rhythm: EKGs
exhibit how fast or slow your heart is beating, and if the beats are
regular or irregular.
- Heart structure: EKGs indicate
the size and configuration of the heart, and possibly any defects you
may have been born with.
Where
is the test performed?
On the
second floor of Sparrow Hospital in the cardiology department Heart Center or on the third floor of the
St. Lawrence Campus.
How
long does this test take?
Approximately
5 minutes.
How
do I prepare for the procedure?
- There is no special
preparation for this procedure.
- Wear a two piece outfit
