Triboelectric noise resulting from motion in the patient vicinity has been observed to occasionally interfere with the ECG. Experiments were performed to verify the nature of the interference and to define the factors which enable this ever-present phenomenon to interfere with ECG acquisition. No instances have been observed that could not be corrected by good electrode placement technique. This study shows that currents produced during the generation or discharge of static electricity can be easily and accurately measured, and the technique used may be applicable to other areas of investigation.
