LBBB AMI

The Sgarbossa criteria can be simplified:
- if see ST elevation in V4-6 of 1mm then that's 5 points
- if see ST depression in V1-3 of 1mm then that's 3points
- if see massive ST elevation in V1-3 (5mm) then that's 2 points...and because this is often seen, you need to get "3" points to be said to have an MI.

Also, you should never have qR complexes in leads V5-6, I, AVL, and interestingly in II, III and AVF.

Then there are 2 eponymous signs:
Cabrera: notching of the ascending part of the S in V3/4
Chapman: notching of the ascending part of the R in V5/6
