Outpatient Services > What to Expect


An electrocardiogram (EKG or ECG) is a fast, painless, noninvasive test used to evaluate the heart by recording its electrical activity. An EKG detects abnormal rhythms and heart muscle damage.

What to expect

On the day of the test, do not use any lotions or powders on your skin. The nurse or technician will cleanse your skin with an alcohol pad and attach a set of small patches, called electrodes, to your chest, arms and legs. It may be necessary to shave some hair so the patches will stick. The patches may feel cold. Wires connect the patches to the EKG machine, which reads the heart activity. Most often, you will lie still during an EKG. In some cases, you may exercise during the test.
