1. An electrode system for reducing motion artifact from an electronic signal, the system comprising:
- an electrode that provides the electronic signal;
a sensor that senses motion and provides a motion signal; and
a controller that determines a noise value based on an analysis of the electronic signal and motion signal, and subtracts the noise value from the electronic signal.

Abstract
An electrode system for reducing noise from an electronic signal, the system including an electrode that provides the electronic signal, and a sensor that senses motion and provides a motion signal. The electrode system includes a controller that determines a noise value based on an analysis of the motion signal, and subtracts the noise value from the electronic signal. The electrode system can reduce or eliminate motion artifact from an electronic signal that can result in misdiagnosis, prolong procedural duration and inappropriate treatment of a patient.
