Oct 8, 2024 · A review of the basic ECG features, causes and pathophysiology of Mobitz I AV Block (Wenckebach Phenomenon) with some example ECGs.

Oct 1, 2024 · Second-degree AV block – Intermittent atrial conduction to the ventricle, often in a regular pattern (eg, 2:1, 3:2), or higher degrees of block, which are further classified into Mobitz type I (Wenckebach) and Mobitz type II second-degree AV block.

Mar 4, 2025 · In Mobitz type I, atrial impulses travelling through the AV node take increasingly longer to fully conduct to the ventricles, until one impulse is completely blocked. On the ECG, this can be seen as a progressive prolongation of the PR interval, until a …

Second-degree AV block Mobitz type I exhibits the Wenckebach phenomenon, which is characterized by a progressive delay in impulse conduction, eventually leading to a blocked atrial impulse.

Jul 25, 2023 · Mobitz type I, also called Wenckebach, is a subtype of a second-degree heart block. In this type of heart block, the signals progressively slow down, causing the heart to drop a beat.

Type 1 Second-degree AV block, also known as Mobitz I or Wenckebach periodicity, is almost always a disease of the AV node. Wenckebach published a paper in 1906 on progressively lengthening PR intervals [10] that was later classified as Type I in Mobitz's 1924 paper. [11] .

A second-degree atrioventricular (AV) block type I is also known as Wenckebach or Mobitz type I. This rhythm occurs at the AV node, where conduction of an electrical impulse is impaired.

Aug 14, 2023 · There are two types of second-degree atrioventricular blocks: Mobitz type I, also known as Wenckebach and Mobitz type II. This activity examines when this condition should be considered on differential diagnosis and how to properly evaluate for it.

Learn about second-degree AV block (Mobitz I & II), ECG features, and ventricular conduction.

Sep 28, 2024 · Type I (Wenckebach): Characterized by a progressively lengthening PR interval followed by a dropped QRS complex (ventricular beat). Type II (Mobitz Type II): This type features a fixed PR interval, with occasional dropped beats. It is often more serious than Type I.
