| Understanding Perpendicular Limb Leads | ||||||||
 |
||||||||
| Class, when we progress to determine the Mean QRS Axis of an EKG rhythm, we need to identify perpendicular leads with the six limb leads. Please see above. Lead I is perpendicular to AVF. Lead II is perpendicular to AVL. Lead III is perpendicular to AVR. In the graphic above I have removed the charges of the Hexaxial reference system for you to focus on the perpendicular leads. | ||||||||
