Electrocardiogram (ECG or EKG)

An electrocardiogram (ECG or EKG) is a test that measures the electrical activity of the heart. When the heart beats, it generates electrical signals that control the heartbeat. The ECG records these signals through small electrodes placed on the skin, creating a graph. This graph helps doctors evaluate the heart’s rhythm, detect irregularities, and identify issues like heart attacks or other conditions. It’s a quick, painless procedure that provides valuable insight into the heart’s health by visually representing its electrical activity over time.
