An electrocardiogram is a simple, painless test that measures your heart’s electrical activity. It’s also known as an ECG or EKG. Every heartbeat is triggered by an electrical signal that starts at the top of your heart and travels to the bottom. An EKG will help your doctor determine the cause of your symptoms along with what type of treatment might be necessary.
If you’re 50 or older or if you have a family history of heart disease, your doctor may also order an EKG to look for early signs of heart disease.
