Electrocardiogram

Electrocardiogram (EKG/ECG) is a test that checks for problems with the electrical activity of the heart. The test converts this activity into line tracings (waves) that can be seen on a monitor and printed out on paper. The interpretation of the spikes and dips in the lines (waves) help a doctor to detect and locate the source of heart problems. At Cardiac Partners, we combine the expertise and experience of our physicians with advanced equipment and software to offer a full range of cardiac studies, including electrocardiogram.

What to expect

A technician will clean the area and place several small, sticky patches (electrodes) on the chest, arms, and legs. A small amount of gel is applied to the skin, which allows the electrical impulses of the heart to be more easily transmitted to the EKG leads. The lead wires will be attached to the electrodes. Once the leads are attached, the EKG is started. It will be important for a person to lie still and not talk during the procedure, so as not to interfere with the tracing. Once the tracing is completed, the technician will disconnect the leads and remove the skin electrodes.
