Infra-Hisian block is that of the distal conduction system. Types of infra-Hisian block include: Type 2 second degree heart block (Mobitz II) – a type of AV block due to a block within or below the bundle of His [5] Left anterior fascicular block; Left posterior fascicular block; Right bundle branch block; Left bundle branch block
Additionally, there is an increased risk of patients with Mobitz II heart block developing third-degree heart block. Therefore, these patients often require temporary pacing with transcutaneous or transvenous pacing wires, and many will ultimately require a permanent implanted pacemaker .
Type 1, called Mobitz 1 or sometimes Wenckebach, happens is when the PR interval gets progressively longer with each beat until a P-wave is blocked completely. So maybe the first PR interval is 200 ms, then the next is 260 ms, then 300 ms, and finally the next one doesn’t make it to the ventricles, and you get what’s called a “dropped ...
