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.
Claims15
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.
A method for reducing motion artifact from an electronic signal, the method comprising:
- providing the electronic signal through an electrode;
- sensing motion through a sensor;
- providing a motion signal based on the sensing of the sensor;
- and
- determining a noise value based on an analysis of the electronic signal and motion signal, and subtracting the noise value from the electronic signal.
A method for reducing motion artifact from differential electronic signals, the method comprising:
- positioning at least two recording electrodes;
- determining the differential electronic signals produced by the recording electrodes;
- determining motion signals;
- and
- analyzing the motion signals;
- and
- determining noise values based on the analysis of the motion signals, and subtracting the noise values from the differential electronic signals.
