   8 paź 2024 · Mobitz II is much more likely than Mobitz I to be associated with haemodynamic compromise, severe bradycardia and progression to 3rd degree heart block. Onset of haemodynamic instability may be sudden and unexpected, causing syncope (Stokes-Adams attacks) or sudden cardiac death.

   Differentiate Mobitz type 1 block from Mobitz type 2 block. Both Mobitz type 1 block and type 2 block result in blocked atrial impulses (ECG shows P-waves not followed by QRS complexes). The hallmark of Mobitz type 1 block is the gradual prolongation of PR intervals before a block occurs.

   12 sie 2022 · Mobitz type II is a type of 2nd degree atrioventricular block, which refers to a cardiac arrhythmia that reflects a conduction block at the atrioventricular (AV) node. On an ECG, Mobitz type II can be identified by the presence of intermittent, non-conducted P waves without progressive prolongation of the PR interval.

   8 paź 2024 · Mobitz II conduction typically produces broad QRS complexes, as it usually occurs in the context of pre-existing LBBB or bifascicular block. This type of fixed ratio block tends to worsen with atropine and is more likely to progress to 3rd degree heart block or asystole.

   6 kwi 2023 · Second-degree AV block – Intermittent atrial conduction to the ventricle, often in a regular pattern (eg, 2:1, 3:2), or higher degrees of block, which are further classified into Mobitz type I (Wenckebach) and Mobitz type II second-degree AV block.
