An electrocardiogram is used to monitor your heart. Each beat of your heart is triggered by an electrical impulse normally generated from special cells in the upper right chamber of your heart. An electrocardiogram — also called an ECG or EKG — records these electrical signals as they travel through your heart.

Your doctor can use an electrocardiogram to look for patterns among these heartbeats and rhythms to diagnose various heart conditions.

An electrocardiogram is a noninvasive, painless test with quick results. Your doctor may discuss your results with you the same day as your electrocardiogram, or at your next appointment.
