electrocardiogram

An electrocardiogram (ECG or EKG) is a test that measures the electrical activity of the heart. It involves placing small sticky electrodes on the skin, usually on the chest, arms, and legs. These electrodes detect the electrical signals generated by the heart as it beats, producing a graphical representation of the heart's rhythm and function. Doctors use ECGs to diagnose heart conditions, monitor heart health, and assess the effectiveness of treatments. The procedure is quick, painless, and non-invasive, providing valuable information about the heart's overall health and electrical activity.
