Mobitz Type II Block Mobitz type II block is usually due toa block below the AV node in the His bundle. It resembles Wenckebach block in that some, but not all, of the atrialimpulsesare transmitted to the ventricles.However, progressive lengthening ...
Recognition of AV Blocks: Second-Degree AV Block Type II (Mobitz II, Infranodal)PathophysiologyThe site of the block is most often below the AV node at the bundle of His or at the bundle branches. Impulse conduction is normal through the node. Thus no first-degree block and no prior PR...

Mobitz II blocks become progressive worse until a complete heart 36、block is established. Thus ,mobitz Type II require a pacemaker, whereas mobitz I does not require a pacemaker, since it does not progress to complete heart block.,Third degree or Complete AV Block (IIIAVB),1).The atrial...
(Image 1)Why is there no second-degree AVB Mobitz type II and no high-grade AV block? To the first question: Basically, second-degree AV block Mobitz type II is rare. The two ECG patterns that can easily be confused with Type II Mobitz block are: blocked/non-conducted PACs and second...
