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 ...

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 ...

Mobitz type I, also known as the Wenckebach block, is a subtype of second-degree atrioventricular (AV) block. Mobitz type I is a type of conduction disorder, which happens when the electrical signals ...

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. It is often benign and ...

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 ...

To the Editor: The article by Dr. M. G. Criscitiello on "Therapy of Atrioventricular Block" implies that Mobitz Type II block may be benefited by atropine or isoproterenol (Isuprel). Type II block may ...

In second-degree AV nodal block (a.k.a. Wenckebach block or Mobitz Type I AV block), varying failure of conduction through the AV node occurs such that some P waves may not be followed by a QRS ...
