Electrocardiogram (EKG)

An electrocardiogram is a cardiac noninvasive diagnostic test that records the electrical activity in all areas of the heart, providing your physician with information about:

  • Your heart rate and heart rhythm
  • The presence of heart damage after a heart attack
  • Inadequate blood and oxygen supply to the heart
  • Abnormalities of the structure of the heart (for example, an enlarged heart)
