My Kaplan instructor told us today that both Mobitz type I and II are due to AV node abnormalities. I just did a usmle-rx question that said Mobitz type I is due to an AV node abnormality which was expected, but it also said Mobitz type II is due to a bundle of His or Purkinje fiber abnormality.

Who is right and what does the usmle say it is? Thanks
