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

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 ...

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 ...

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, ...

Figure 1: Measurement of gene transfer efficacy. Figure 2: Reduction in heart rate during atrial fibrillation after Gα i2 gene transfer. This study is the first report of intracoronary site-specific ...

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 ...

The heartbeat originates from spontaneous depolarizations in the sinoatrial node, which lead to the spread of electrical signals throughout the heart via a specialized conduction system Failure of the ...
