I've seen that while beginning to learn EKG tracings, some people have difficulty finding the perpendicular axes in the frontal plane. I'm talking of course, about the axes found in Standard and Augmented leads.

You can look at it on the EKG paper like the image below,

but when unavailable:

the mnemonic is REFILL

R = aVR
E = DIII, letter E has "three arms"

F = aVF
I = DI

L = aVL
L = DII, double L

It helped me.

Thank you.
