In regards to the question "which artery would be responsible for an inferior damage to the heart" you mentioned right circumflex artery but I believe it is Right Coronary Artery. 

I could be incorrect, I'm still learning but I wanted to clarify in case it was just a slip of the tongue.

Thank you for your videos!

I believe you have II and III reversed in the figure? Lead II is supposed to view the heart from the PT's left side, looking up through the apex of the heart, but you referred to that lead location as III. 

Also, AVR is the exact opposite side of the heart from lead II (the apex), not of AVL. AVR sits on the right shoulder and looks down from the atrium to the apex, AVL sits on the left shoulder and looks pretty much perpendicular to the axis of the heart from the left lateral surface.
