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 ...

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 ...

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 ...

Objective:To identify the frequency of atrioventricular (AV) conduction improvement after discontinuation of the culprit drug in patients with AV block. Background:AV blockers are considered as ...

20% of cases of autoimmune CHB are fatal and 64% of live births require a pacemaker 1.7% of pregnant women positive for anti-Ro or anti-La antibodies have a baby with autoimmune CHB, but the risk ...

Second-degree heart block is a potentially serious but treatable condition affecting the heart’s electrical system. Treatment may require a pacemaker to stabilize the heart’s rhythm. Electrical ...

In second degree type II AV nodal block (a.k.a. Mobitz Type II AV block), the AV node becomes completely refractory to conduction on an intermittent basis. For example, three consecutive P waves may ...

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 ...
