Electrocardiogram

An electrocardiogram (also called EKG or ECG) is a test that records the electrical activity of your heart through 10 small electrode patches attached to the skin of your chest, arms, and legs. An EKG may be part of a complete physical exam or it may be used to further investigate symptoms related to heart problems.

Your doctor uses the EKG to:

  • Assess your heart rhythm
  • Diagnose poor blood flow to the heart muscle (ischemia)
  • Diagnose a heart attack
  • Evaluate certain abnormalities of your heart, such as an enlarged heart
