There are two subtypes of second-degree heart block: Mobitz type 1 (also called a Wenckebach block), which may or may not cause symptoms, and Mobitz type 2, which can cause problems pumping blood ...

Mobitz type 2 heart block occurs when the electrical impulses between the atria and the ventricles are intermittent. There are four chambers in the heart, with two on the top and two on the bottom.

This type of heart block is also known as Wenckebach. Mobitz type 2: In Mobitz type 2, some beats are completely blocked while others are not, resulting in an irregular heartbeat.

A diagnosis of Mobitz type I — also called “Wenckebach heart block” — means the impulses from the sinus node get slower and slower. Occasionally, the heart skips a beat entirely.

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 ...

For example, in Wenckebach phenomenon, a 5:4 AV conduction ratio becomes 4:3, then 3:2, and can eventually become 2:1 (a 2:1 AV conduction ratio can be the shortest Wenckebach cycle).

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 ...

Second-degree block comes in two varieties: type I (Wenckebach), which you have, and type II, which usually requires a pacemaker since it often proceeds to type III, complete heart block, which ...

Type I: This is also called Mobitz Type I or Wenckebach’s AV block. It’s a less severe form of second-degree heart block and is characterized by gradually slower electrical activity to the ...

Experts break this form of heart block into three subtypes: Second degree heart block Mobitz type I — also called Wenckebach heart block — second degree heart block Mobitz type II, and second ...

There are three main types of heart block, and depending on the type, symptoms and treatment vary. First-degree heart block is the mildest type and often requires no treatment.

The two types of second-degree heart block are Mobitz type I (Wenckebach) and Mobitz type II, which is generally the more serious of the two. In Mobitz type I, the PR interval is gradually ...
