You can infer the heartís mechanical activity from the ECG. The electrical events of the heart are usually recorded on the ECG as a pattern of a baseline broken by a P wave, a QRS complex, and a T wave. The baseline (isoelectric line) is a straight line on the ECG. WebThe electrical activity of the heart is measured by an electrocardiogram. By placing electrodes at specific locations on the body (chest, arms, and legs), our specialists can get a “picture,” or tracing, of the electrical activity in the heart. Changes in an ECG from the normal tracing can show one, or more, of several heart-related conditions. fernbees day nursery
