ECG stands for electrocardiogram. It records the electrical activity of heart in the form of waves. This happens due to the depolarization and repolarization of the heart. Deviations from the normal ECG is indication of heart problems and disease. There are three components of the ECG

P wave: Depolarization of auricles
QRS complex: Depolarization of ventricles
T wave: Repolarization of ventricles.
