An electrocardiogram or EKG is the most frequently used test for the evaluation of possible heart disorders. Small adhesive pads are applied to the skin on each arm, leg, and on the chest. These pads (electrodes) act as antennas and receive electrical impulses from the heart. The electrical energy is then transferred to an EKG machine for processing and display on graph paper. The EKG is included in the patient's hospital record, and your physician uses it in planning the proper treatment. There are variations on this test, and EKG's are frequently repeated at regular intervals for comparison.

Reasons for this test:

  • Identification of abnormalities, cardiac disturbances, heart disease
  • To determine the site and extent of a heart attack
  • To monitor recovery from a heart attack
  • To evaluate effectiveness of cardiac medications
  • To observe pacemaker function

Preparations for the Exam

  • The chest must be exposed to apply the electrodes
  • The patient is required to lie still for approximately two minutes while two EKG's are taken
