Q. Can you explain Likar System with Electrodes?

The 12 lead Mason - Likar system with electrodes is used. The plastic adhesive electrodes has self contained electrode jelly in the cap and need only to be stuck on and attached to the lead wire. A few minutes delay between application and exercise allows for better contact and therefore, less battery effect at the skin contact point. This minimizes the baseline wandering. It is very important the right and left arm electrode be placed laterally rather than in the mid clavicular line as is sometimes done.
