Why it's doneBy Mayo Clinic staff
An electrocardiogram is a painless, noninvasive way to diagnose many common types of heart problems. Your doctor may use an electrocardiogram to detect:
- Irregularities in your heart rhythm (arrhythmias)
- Heart defects
- Problems with your heart's valves
- Blocked or narrowed arteries in your heart (coronary artery disease)
- A heart attack, in emergency situations
- A previous heart attack
