The electrode is a fundamental part of the electrocardiogram (ECG) system. It is the interface between the body and the measuring equipment that allows us to measure and record the ECG.

When recording the ECG, we experience artifacts that can be caused by mains noise, motion and potentials from other muscles. These sources of artifact can distort or attenuate the ECG and result in an increased number of false-positive alarms from automated ECG interpretation systems.
