Electrocardiogram (ECG or EKG)

The electrocardiogram (ECG or EKG) is a test that is used to view heart conditions by measuring the electrical activity of your heart. ECG electrodes or small patches with a special gel that allows the electrical impulses to be tracked are placed on your body in various locations, connected with special wires to the ECG machine.

What is measured or can be detected on the ECG (EKG)?

  • The rate and rhythm of your heart
  • The location and placement of your heart in your chest cavity
  • Increased thickness (hypertrophy) of your heart walls
  • Any damage to the various parts of your heart
  • Any blocked blood flow to your heart
  • Abnormal electric activity that could lead to abnormal cardiac rhythms
