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 ...

Mobitz type I, also known as the Wenckebach block, is a subtype of second-degree atrioventricular (AV) block. Mobitz type I is a type of conduction disorder, which happens when the electrical signals ...

All cases admitted or discharged from our institution between January 2008 and June 2009 with a diagnosis of AV block were reviewed. In addition, beginning in June 2009, data from all patients ...

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

Patients with atrioventricular (AV) block who don’t have an indication for cardiac resynchronization therapy (CRT) do better when treated with conduction-system pacing versus right ventricular septal ...

NEW YORK, NY—High-grade atrioventricular (AV) block occurs within 1 month for roughly one in seven patients who undergo transcatheter tricuspid valve replacement (TTVR), according to new results from ...

First-degree ventricular (heart) block affects the electrical signal that makes the heart beat. It causes a delay in a portion of the heart beat and may lead to a slow heart beat. Healthcare ...

Heart block in patients younger than 65 years is unlikely to be caused by degenerative conduction system disease. A complete evaluation for secondary causes of heart block should be undertaken before ...
