The diagnosis of first-degree and third-degree atrioventricular (AV) block is straightforward but that of second-degree AV block is more involved. Type I block and type II second-degree AV block are electrocardiographic patterns that refer to the behaviour of the PR intervals (in sinus rhythm) in sequences (with at least two consecutive conducted PR intervals) where a single P wave fails to conduct to the ventricles. Type I second-degree AV block describes visible, differing, and generally decremental AV conduction. Type II second-degree AV block describes what appears to be an all-or-none conduction without visible changes in the AV conduction time before and after the blocked impulse. The diagnosis of type II block requires a stable sinus rate, an important criterion because a vagal surge (generally benign) can cause simultaneous sinus slowing and AV nodal block, which can resemble type II block. The diagnosis of type II block cannot be established if the first post-block P wave is followed by a shortened PR interval or by an undiscernible P wave. A narrow QRS type I block is almost always AV nodal, whereas a type I block with bundle branch block barring acute myocardial infarction is infranodal in 60–70% of cases. All correctly defined type II blocks are infranodal. A 2:1 AV block cannot be classified in terms of type I or type II block, but it can be AV nodal or infranodal. Concealed His bundle or ventricular extrasystoles may mimic both type I or type II block (pseudo-AV block), or both
