Q

ECG - axis lead positions and nrm/left/right axis deviation strategy

A 
aVR, aVF, aVL - make a Y
(going clockwise)
right - aVL, I
bottom - II, avF (mid), III
left - aVR
strategy:
1 - positive deflection, use std position and go out 90 degrees both directions for 180 total 
2 - negative deflection, flip std position and go out 180
3 - match the leads, area of most overlap = nrm/left/right
left deviation = -30 to -90
nrm = -30 to + 90
right deviation = +90 to +180
*remember electric goes down to left
