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 ...

The atrioventricular node (AV Node) is a bundle of conduction cells that regulate the communication of atrial electrical activity with ventricular electrical activity. The AV node has a long ...

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 ...

In patients with atrioventricular septal defect (AVSD), the occurrence of nonsurgical AV block has been reported. We have looked for an explanation in the development of the AV conduction system.

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 ...

Abnormal heart rhythms (dysrhythmias) are caused by disturbances in electrical impulse generation or by abnormal conduction between chambers of the heart – principally within the sinus node, ...

This Journal feature begins with a case vignette highlighting a common clinical problem. Evidence supporting various strategies is then presented, followed by a review of formal guidelines, when they ...
