An electrocardiogram
(EKG or ECG) is a test that checks for problems with the electrical activity
of your heart. An EKG translates the heart’s electrical activity
into line tracings on paper.
Why is it done?
An electrocardiogram
(EKG or ECG) is done to:
Evaluate the heart's
electrical activity.
Find the cause
of symptoms of heart disease, such as chest pain, shortness of breath,
dizziness, fainting, or rapid, irregular heartbeats (palpitations).
Find out if the
sac surrounding the heart is inflamed (pericarditis) or the walls of
the heart chambers are too thick (hypertrophied).
Evaluate how well
medicines are working and whether they are causing side effects that
affect the heart.
Evaluate the health
of the heart when other diseases or conditions are present, such as
high blood pressure, high cholesterol, cigarette smoking, diabetes,
or a family history of early heart disease.
