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 ...

The diagnosis is right bundle branch block, left anterior fascicular block, Mobitz type I (Wenckebach) with 2:1 and 3:2 atrioventricular conduction (Figure 2). The rhythm is regular, except for the ...

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 ...

In the treatment of atrioventricular block, dual-chamber cardiac pacing is thought to confer a clinical benefit as compared with single-chamber ventricular pacing, but the supporting evidence is ...

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 ...
