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.
