An electrocardiogram or ECG/EKG is a painless and non-invasive test recording the electrical activity of the heart.


Use of ECG/EKG
It shows:

  • How fast the heart is beating
  • Whether the rhythm of the heartbeat is steady or irregular
  • The strength and timing of electrical signals as they pass through each part of the heart
  • Poor blood flow to the heart muscle (ischemia)
  • Certain abnormalities of the heart, such as an enlarged heart
  • Recovery from a heart attack, progression of heart disease, or the effectiveness of certain heart medications or a pacemaker
