Type II second-degree AV block or Mobitz type II is less frequent, and almost always means severe disease of the conduction system 3. It differs from the type I second-degree AV block by constant PR intervals, before and after the blocked P wave. ECG Examples of Fixed Ratio AV blocks 2:1 block The atrial rate is approximately 75 bpm. The ventricular rate is approximately 38 bpm. 2:1 atrioventricular block is a form of second-degree AV nodal block and occurs when every other P wave is not conducted through the AV node to get to the ventricles, and thus every other P wave Second-degree AV block occurs when the electrical signal between the atria and ventricles is even more impaired than in a first-degree AV block. In a second-degree AV block, the impairment results in a failure to conduct an impulse, which causes a skipped beat. Mobitz type II 2nd-degree AV block is always pathologic; the block occurs at the His bundle in 20% of patients and in the bundle branches in the rest.
