Limb Lead Placement — ECG Academy Lesson

How limb-electrode setup determines the six frontal-plane views you monitor, why Lead II is the default, and what common wiring errors look like.

Learning Objectives

• Recognize the correct torso electrode positions for RA, LA, RL, and LL
• Apply AHA color coding standards using reliable memory aids
• Describe what each of the six limb leads "sees" in terms of cardiac electrical activity
• Explain why Lead II is the preferred monitoring lead for rhythm surveillance
