An EKG is a test that records the electrical activity of the heart. An EKG is used to measure the rate and regularity of heartbeats, the presence of any damage to the heart, and the effects of drugs or devices used to regulate the heart (such as a pacemaker).

How the test is performed:

  • You will be asked to lie down, and electrodes will be affixed to each arm and leg and to your chest. This requires cleaning the site and, if necessary, shaving or clipping hair. The standard number of leads attached is 12.

  • You need to remain still, and you may be asked to hold your breath for a few seconds during the procedure.

  • The results are printed out on graph paper.

How to prepare for the test:

  • Please refrain from using any lotions on your skin prior to your visit so that the EKG patches better adhere to your skin.
