Electrocardiograhy (EKG or ECG) is a test. It is used to check the heart. It looks at your heartbeat, heart size, and can tell if you have had a heart attack. No electricity will flow into your body during the test.


  • You will remove your clothes from the waist up, wear a hospital gown, and lie down on your back.

  • Small round pads (electrodes) will be placed on your arms, legs, and chest. The round pads are attached to wires that go to an EKG machine. The EKG machine records the electrical activity of your heart.

  • You will be asked to relax and lie very still for a few seconds.

  • The EKG takes a few minutes.


  • If the EKG was done as part of a routine exam, you can go back to your normal activity as told by your doctor.

  • If the EKG was done because you were having chest pain, you may need to have more testing for your safety.

  • Your EKG results will be looked at by a heart doctor (Cardiologist).
