Electrocardiogram (EKG)

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. The patient is asked to remain very still while the 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. Qualified medical staff interpret the graphed results to determine any irregularities. 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 is 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, 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.
