The diagnosis is NSR, first-degree AV block, 3:1 AV block, Mobitz type II, and high-degree AV block. The rhythm is regular with a rate of 30 beats/min. The QRS complex duration is normal (0.08 sec) ...

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 ...

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 ...

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 ...

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 ...
