An electrocardiogram, called an EKG, is a test that measures the electrical activity of the heart. With each beat, an electrical impulse or wave travels through the heart. This wave causes the heart muscle to squeeze and pump blood to the lungs and the rest of the body.

When Do You Need an EKG?

An EKG is a safe, painless test. Your doctor might order an EKG to see if you have heart-related problems. It can help:

  • Evaluate your heart's electrical activity
  • Investigate the cause of unexplained chest pain, shortness of breath, dizziness or rapid and irregular heartbeats
  • Determine how well medicines are working and if they’re causing side effects
  • See how well pacemakers and other mechanical devices are working
  • Evaluate the health of the heart when other diseases or conditions are present, such as high blood pressure or high cholesterol, diabetes or a family history of early heart disease
