Wow !I always use the quick and dirty method for determining axis that I learned from an anesthesia attending. Here's what you do:
1) Look at EKG
2) Put both of your fists in front of you and make two "thumbs up" signs
3) Think of your left thumb as Lead I and your right thumb as aVF
4) Look at the QRS complex in I and aVF on the EKG
5) Point your respective thumb in the direction of the respective QRS
Both thumbs up = normal axis
Left up/right down = left axis deviation
Right up/left down = Right axis deviation
Both down = lead misplacement, try again
This method is accurate ~95% of the time
Impressive indeed !!!
