The Leads

How do you place the electrodes for the limb leads?

Europe: Red electrode on the right arm. We then continue clockwise using the traffic light system: a yellow electrode is placed on the left arm, and a green electrode is placed on the left leg. The grounding lead is attached to a black electrode, which is placed on the right leg.

North America: The white electrode is used for the right arm, black for the left arm, red for the left leg, and green for the right leg.
