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 ...

2:1 atrioventricular block is a form of second-degree AV nodal block and occurs when every other P wave is not conducted through the AV node to get to the ventricles, and thus every other P wave is ...

A first-degree atrioventricular node block occurs when conduction through the AV node is slowed, thereby delaying the time it takes for the action potential to travel from the sinoatrial node through ...

Although there have previously been no reported cases of an interaction between trazodone and omeprazole, a new report is believed to be the first instance of reversible second-degree Mobitz type 1 ...

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 ...
