2:1 AV-block

These two pages show the transition of a second degree type I block (Wenckebach) to what appears to be a second degree type II block.  See the comments by Vince DiGiulio

  1. It's pretty uncommon for a block to change "type" right in front of you. What we're dealing with here is all type I AV-block, it's just changing conduction ratios from 3:2 to 2:1. Not all 2:1 block is type II—in fact, most is probably type I.
