The correct diagnosis is sinus rhythm, second-degree AV block with 2:1 conduction, Mobitz type II (Figure 2). There is a regular rhythm at a rate of 42 beats/min, although the last QRS complex is ...

The correct diagnosis is sinus rhythm with 2:1 AV block due to Mobitz type II; ventriculophasic arrhythmia (Figure 2). The rhythm is regular at a rate of 40 beats/min, although the fifth QRS complex ...

Mobitz type I, also known as the Wenckebach block, is a subtype of second-degree atrioventricular (AV) block. Mobitz type I is a type of conduction disorder, which happens when the electrical signals ...

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 may ...
