In second-degree atrioventricular nodal block — also known as Wenckebach block or Mobitz Type I AV block — varying failure of conduction through the AV node occurs, such that some P waves may not be ...

The diagnosis is right bundle branch block, left anterior fascicular block, Mobitz type I (Wenckebach) with 2:1 and 3:2 atrioventricular conduction (Figure 2). The rhythm is regular, except for the ...

Transplacental transfer of anti-Ro antibodies is a well-known cause of conduction defects and permanent atrioventricular block in newborns. 1 In adults, conduction disturbances related to these ...

There are P waves (+) with regular PP intervals and a rate of 85 beats/min. The P waves have a normal morphology; they are positive in leads I, II, aVF, and V4-V6. This is a stable normal sinus rhythm ...
