An electrocardiogram (EKG) or (ECG), is a medical test that records the heart’s electrical activity. It’s one of the most administered tests in medicine and for cardiac patients.
An EKG gives medical professionals a glimpse into the heart’s activity to assess its health from that recorded data, including detecting heart abnormalities. These tests are performed in
hospitals, ambulances, doctor’s offices, and other medical care settings. EKG prep is done in
advance of the actual EKG monitoring.
