ECG (Electrocardiogram)

An electrocardiogram (ECG or EKG) is a medical test that records the electrical activity of the heart over a period of time. Small electrodes are placed on the skin to detect the heart's electrical signals, which are then displayed as waves on a monitor or printed on paper. Doctors use ECGs to assess heart health, identify irregular heart rhythms, detect heart damage, and diagnose various heart conditions. The test is quick, non-invasive, and provides valuable information about how well the heart is functioning.
