EKG or
Electrocardiogram |
 |
Electrocardiogram, EKG or ECG: An EKG is
an important part of the initial evaluation of a patient who is
suspected to have a heart related problem. Small sticky electrodes are
applied to the patient's chest, arms and legs. However, with some
systems, the electrodes may be applied to the chest, shoulders and the
sides of the lower chest, or hips . Wires are used to connect the
patient to an EKG machine. You will be asked to remain very still while
a nurse or technician records the EKG. The electrical activity created
by the patient's heart is processed by the EKG machine and then printed
on a special graph paper. This is then interpreted by your physician. It
takes a few minutes to apply the EKG electrodes, and one minute to make
the actual recording. |

The EKG is extremely safe and there is no risk involved. In rare cases,
some people may develop skin irritation from the electrode adhesive, but
no serious allergic reactions have been reported.

The only
preparation for an EKG to wear clothes that allow easy access to your
chest. Thus, a blouse or shirt with buttons down the front is a lot more
practical than a pantsuit or dress. Once you arrive in your doctor's
office or in the hospital, your chest may be cleansed with alcohol to
ensure good electrical contact with the EKG electrode. In men with hairy
chest, small areas may have to be shaved to allow adequate skin contact
with the electrode. This avoids interfering artifacts from being
recorded on the EKG and produces a technically satisfactory study. |

The EKG can provide important information about the patient's heart
rhythm, a previous heart attack, increased thickness of heart muscle,
signs of decreased oxygen delivery to the heart, and problems with
conduction of the electrical current from one portion of the heart to
another. |

It is important to
remember that EKGs are not 100% accurate. Normal recordings can be
obtained in patients with significant heart disease, or some
"abnormalities" may exist in the presence of a normal heart. |
