An electrocardiogram (ECG or EKG) is a test that measures the electrical activity of the heart. It is often used to detect and diagnose heart problems such as abnormal rhythms, damage to the heart muscle, and other heart-related conditions. A coronary arteriogram is a test that uses X-rays to examine the blood vessels of the heart. An electroencephalogram (EEG) is a test that measures the electrical activity of the brain. An echocardiogram is a test that uses ultrasound to produce images of the heart to assess its structure and function.
