Therefore, altering AV nodal conduction would have no effect. To distinguish between the two potential rhythms when an ECG reveals 2:1 AV nodal block, a few different maneuvers can be employed: ...

Mobitz type 1 heart block may not cause any symptoms. A doctor may only discover the condition during a routine exam or when checking for other conditions using an ECG.

There are three types of second degree heart block, also called atrioventricular (AV) block. In type I the signal sometimes does not reach the ventricles, causing skipped beats.

Discussion 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 ...

A decrease in blood flow to the AV nodal artery (a branch of the RCA) can result in AV nodal ischemia and AV conduction abnormalities such as the second-degree type II AV block seen in the ECG.
