There are two different kinds of second-degree heart block: Mobitz type 1 and Mobitz type II. Mobitz type II may require a pacemaker or other treatments to maintain a healthy heart rhythm.

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.

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 ...

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 ...

An atrioventricular block causes the heart beat more slowly or with an abnormal rhythm. It's caused by a problem with the electrical pulses that control how the heart beats and is diagnosed in stages.

An AV block is when electrical signals get delayed for too long at the AV node or the His-Purkinje system. ... This ECG shows a Mobitz Type 1 Second Degree Atrioventricular Block.

In second-degree atrioventricular nodal block — also known as Wenckebach block or Mobitz Type I AV block — varying failure of conduction through the AV node occurs, such that some P waves may ...
