Overview

Explanation

The three electrode system displays leads I, II, and III, and are placed on the chest wall equi-distant from the heart instead of over limbs. Some leads are red, yellow, and green (European standard color coding). If those colors are present: RA = Red; LA = yellow; LL = green. The nurse must be familiar with policies and which type of lead coding is used.
