ECG TEST

An electrocardiogram (ECG or EKG) records the electrical signal from your heart to check for different heart conditions. Electrodes are placed on your chest to record your heart's electrical signals, which cause your heart to beat

Why it's done

An electrocardiogram is a painless, noninvasive way to help diagnose many common heart problems in people of all ages. Your doctor may use an electrocardiogram to determine or detect

  • Abnormal heart rhythm (arrhythmias)
  • Whether you have had a previous heart attack
  • How well certain heart disease treatments, such as a pacemaker, are working
  • If blocked or narrowed arteries in your heart (coronary artery disease) are causing chest pain or a heart attack
