An EKG is an electrical recording of your heart. The machine does not send electricity into the body. Instead, it receives tiny electrical impulses from the heart's beating and records them onto a strip of paper. An EKG is used to check for damage to the heart and for any heartbeat irregularities.
Your Medical Assistant will perform your EKG, attaching 10 electrodes to your body. The test takes about 1-2 minutes and the results will be immediately reviewed with you by your provider.
