Electrocardiography (ECG)

Electrocardiography (ECG or EKG) is a medical test that records the electrical activity of the heart over a period of time. By placing small, sticky electrodes on the skin, it captures the heart's rhythm and electrical signals. The results are displayed as waves on a graph, helping doctors identify heart conditions like arrhythmias, heart attacks, and other abnormalities. An ECG is non-invasive, quick, and painless, making it a valuable tool in assessing heart health and guiding treatment decisions.
