Atrioventricular blocks occurring during transcatheter aortic valve replacement differ from those occurring after 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 ...

Third-degree atrioventricular nodal block, also known as third-degree heart block or complete heart block, occurs when no action potentials conduct through the AV node. This results in the P waves ...

Some consider 2:1 AV block to be type II block, claiming that the PR interval doesn't lengthen. What they don't realize is that determining whether the PR interval lengthens requires at least 2 ...

Right ventricular pacing restores an adequate heart rate in patients with atrioventricular block, but high percentages of right ventricular apical pacing may promote left ventricular systolic ...

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 ...

Heart block is a disruption in the electrical signals that control your heart. Your heart depends on a steady flow of electrical signals that start in the heart’s upper chambers (atria). The signals ...
