I teach this class. I like the "renter" analogy.

Remember this little phrase every time you look at a 12 lead. "I see all leads."

I: Inferior wall- look at II, III, AVF

See: Septal wall- look at V1 & V2

All: Anterior wall- V3 & V4

Leads: Lateral Wall- What is left over? V5, V6, I, & AVL

Remember: you can write AVR off.

A down and dirty cheat for bundle branch blocks. Look at V1, find the J point, and draw a line back through the QRS. If the triangle you create goes up, it's a RBBB. Down, it;s a LBBB. This is called the turn signal criteria and is quite accurate.
