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

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 …

In Wenckebach's 1906 paper, his original observations were of increasing delay in contraction of the atria and ventricles that shortened after a brief pause. He later observed this in the …

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 …

Mar 31, 2024 · Wenckebach arrhythmia, also known as Mobitz type I second-degree atrioventricular (AV) block, is a cardiac rhythm disorder characterized by a delay in the …

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.

Mar 4, 2025 · Mobitz type I, also known as Wenckebach block, is a type of 2 nd degree AV block, which refers to a cardiac arrhythmia that reflects a conduction block at the atrioventricular AV …

Jun 13, 2025 · Second-degree type I AV block, also known as Mobitz I or Wenckebach, is typically characterized by a progressive prolongation of the PR interval followed by a dropped …

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 …

Another way of thinking of this is there is a progressively prolonged delay in the AV node until there is an instance where the impulse does not pass through the AV node. A common way to …
