ELECTROCARDIOGRAPHY

Your doctor may suggest you get an electrocardiogram -- also called an EKG or ECG -- to check for signs of heart disease. It's a test that records the electrical activity of your heart through small electrode patches that a technician attaches to the skin of your chest, arms, and legs.

EKGs are quick, safe, and painless. With this test, your doctor will be able to:
 
  • Check your heart rhythm
  • See if you have poor blood flow to your heart muscle
  • Diagnose a heart attack  
  • Check on things that are abnormal, such as thickened heart muscle
