What is Mobitz type I? Mobitz type I is a type of 2 nd degree AV block, which refers to an irregular cardiac rhythm (arrhythmia), that reflects a conduction block in the electrical conduction system of the heart. Mobitz type II is a type of 2 nd degree AV block, which refers to an irregular cardiac rhythm (i.e., arrhythmia) caused by a block in the electrical conduction system of the heart.
The heart is a muscular organ composed of four chambers: two upper chambers (the right and left atria) and two lower chambers (the right and left ventricles). The chambers of the heart are wired with an electrical ... Second-degree Mobitz type II AV block is characterized by a stable PR interval with dropped beats, and it most often occurs in patients with underlying heart disease. Treatment typically requires permanent pacemaker implantation.

mobitz type 2, Type I, called “Mobitz I,” or sometimes “Wenckebach,” happens when the PR interval gets progressively longer with each beat until a P wave is blocked completely. Now, Mobitz 2 blocks can sometimes progress to our next type, the dangerous 3rd degree AV block. In this type, none of the electrical impulses are conducted through the AV node, and that’s why it’s also called complete heart block. The correct diagnosis is sinus rhythm with high-degree atrioventricular (AV) block (ie, Mobitz II) (Figure 2). Figure 2. Courtesy of Philip J.
