I'm trying to figure out what makes this variable.

ok you see the P waves and T waves right after the QRS the distance is too far apart in other words it is taking the heart to depolorize and repolorize

im in the hospital right now after i feel off my horse they found out my heart beat was low and they just told me this is what i have

On this example the P:QRS is constant and we see a permanent 4:3 Block .

An 3:1 or 4:1 Block is typical for "advanced AV Block" - this has nothing to do with Mobitz II.
