  UW is telling that "mobitz 1 improves with atropine and mobitz 2 worsens with atropine" if it is so, then why in patients with mobitz 2 we use atropine (hemodynamically unstable mobitz 2) ???

  With Mobitz-II, aka, second-degree AV block type II, there is a partial block in the electrical impulses from the atria (SA) to the ventricles, and thus the effects of atropine would not significantly change the status of the ventricles. This block can also rapidly progress to 3rd-degree block.

Atropine may speed the firing rate of the SA node (atria), but the ventricles are not responding to anything the atria (SA node) puts out. Thus, the heart rates will not increase.

Found this online on an ACLS website. Good Luck and thanks for asking the question.
