2:1 atrioventricular block is a form of second-degree AV nodal block and occurs when every other P wave is not conducted through the AV node to get to the ventricles, and thus every other P wave is ...

Some consider 2:1 AV block to be type II block, claiming that the PR interval doesn't lengthen. What they don't realize is that determining whether the PR interval lengthens requires at least 2 ...

This ECG has both second degree AV block with 2:1 block and second degree type I AV block. Note that intermittent P waves conduct to the ventricles on this ECG tracing, however it is clear that some ...

All cases admitted or discharged from our institution between January 2008 and June 2009 with a diagnosis of AV block were reviewed. In addition, beginning in June 2009, data from all patients ...

The mechanism of 2:1 atrioventricular block in infants with the congenital long QT syndrome has been postulated to result from a long ventricular effective refractory period interrupting conduction of ...

Although there have previously been no reported cases of an interaction between trazodone and omeprazole, a new report is believed to be the first instance of reversible second-degree Mobitz type 1 ...

This guidance refers only to pacing for the primary indications of sick sinus syndrome and/or atrioventricular block, and does not cover more complex pacing indications. Dual-chamber pacing is ...
