Abstract

During the operation, it is difficult to continuously record the EKG, because the various noises present. Most important problem is a high frequency (HF) interference from the electrosurgical unit (ESU). There are three routes that the HF interference passes through a patient body as follows1);
  1. 1.

    Conduction through the alternating current (AC) power line

     
  2. 2.

    Radiation; HF interference is transmitted via electric and magnetic field coupling into the monitoring circuit cable

     
  3. 3.

    Conduction directly through a patient into the monitoring device
