ECG: ElectroCardioGram

The full form of ECG is electrocardiogram. It refers to a test that measures the electrical activity of the heart to show whether or not it is working normally. An ECG records the heart’s rhythm and activity on a moving strip of paper or a line on a screen. The ECG is one of the most commonly used medical studies in the assessment of cardiovascular disease. It is the most important test for interpretation of the cardiac rhythm, detection of myocardial ischemia and infarction, conduction system abnormalities, preexcitation, long QT syndromes, atrial abnormalities, ventricular hypertrophy, pericarditis, and other conditions.

Electrocardiogram (ECG) records the electrical impulses when the heart is beating. These impulses are recorded on a moving strip of paper or on a screen, i.e. it shows heart’s electrical activity as line tracings on paper. The spikes and dips that appear in the tracings are called waves. There are three main components to an ECG: the P wave, which represents the depolarization of the atria; the QRS complex, which represents the depolarization of the ventricles; and the T wave, which represents the repolarization of the ventricles.
