WebbElectrocardiogram (ECG): Electrocardiogram (ECG) is a record of changes in electrical potential across the heart during one cardiac cycle. If electrodes are properly placed on the surface of the body, the electrical potentials generated by the heart can be recorded. This record is called ECG and the apparatus is known as an electrocardiograph.

WebbIn addition to the P wave, QRS complex, and T wave, other features of ECG signals can also provide important information about cardiac function. For example, the PR interval represents the time between the start of the P wave and the start of the QRS complex and can indicate abnormalities in atrioventricular conduction. WebbFigure 1 shows a complete ECG cycle in which the P wave, QRS bundle, and T wave are the most important characteristic waves.
