Second-degree heart block is a type of heart rhythm disorder. There are two types of second degree heart block — Mobitz type 1 and Mobitz type 2. Mobitz type 2 heart block occurs when the electrical ...

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) ...

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 ...

The correct diagnosis is sinus rhythm with high-degree atrioventricular (AV) block (ie, Mobitz II) (Figure 2). Figure 2. Courtesy of Philip J. Podrid, MD. The rhythm is regular, at a rate of 30 ...

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 ...

In the treatment of atrioventricular block, dual-chamber cardiac pacing is thought to confer a clinical benefit as compared with single-chamber ventricular pacing, but the supporting evidence is ...

The mechanism of 2:1 atrioventricular block in infants with the congenital long QT syndrome has been postulated to result from a long ventricular effective refractory period interrupting conduction of ...

We present a case of a 57-year-old man with congenitally corrected transposition of the great arteries (ccTGA), enlarged left atrium, systemic morphologically right ventricle with ejection fraction of ...

In second-degree AV nodal block (a.k.a. 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 followed by a QRS ...
