Blocked premature atrial beats must be differentiated from Mobitz II AV block. Blocked atrial beats will occur earlier than expected compared with the fixed PP interval in Mobitz II AV block. Atrial fibrillation with a slow heart rate may indicate second-degree AV block.
WebAtrioventricular dissociation should not be confused with third-degree AV block. AV dissociation results from a marked slowing of the sinus node or atrial bradycardia or acceleration of the AV node. Whereas in AV dissociation, the atrial rate is slower than the ventricular rate, in complete heart block, the ventricular rate is usually slower ...
