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.

This combination is a trifascicular block and syncope should concern the clinician for 3rd degree AV block. The presence of a trifascicular block indicates significant conduction disease is present.

SAN FRANCISCO -- Better indicators of high-grade atrioventricular (AV) conduction system abnormalities following transcatheter aortic valve replacement (TAVR) could be gleaned from an intraprocedural ...

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 ...

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 ...

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 ...

To the Editor: The article by Dr. M. G. Criscitiello on "Therapy of Atrioventricular Block" implies that Mobitz Type II block may be benefited by atropine or isoproterenol (Isuprel). Type II block may ...

Our elderly population (over 70 years) with dual-chamber pacemakers inserted for complete AV block benefit significantly from DDD pacing compared with VVIR pacing. There were improvements in HRQoL ...
