Which color represents the right leg electrode?

The correct color representing the right leg electrode is green. In standard ECG (electrocardiogram) lead placement, color coding is used to ensure consistency and accuracy in positioning electrodes. The right leg electrode is assigned the color green according to the most commonly utilized American Heart Association (AHA) standards for limb leads.

Typically, the color coding for the limb leads is as follows:

• Right arm: White

• Left arm: Black

• Left leg: Red

• Right leg: Green

Using this consistent color scheme helps healthcare providers quickly identify the electrodes' placements during procedures. It’s essential to understand these color codes to avoid confusion and ensure accurate electrode placement, which is crucial for obtaining reliable results from the ECG.
