When high doses of AV blocking drugs are not successful to lower ventricular rates in the setting of atrial fibrillation, AV node ablation can be utilized. Remember that all atrial action potentials ...

The atrioventricular node (AVN) has mystified generations of investigators over the last century and continues today to be at the epicenter of debates among anatomists, experimentalists, and ...

February 22, 2012 (Adelaide, Australia) — Atrioventricular (AV) nodal ablation significantly improves survival in heart-failure patients with atrial fibrillation (AF) who receive cardiac ...

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 ...

Atrioventricular nodal reentrant tachycardia (AVNRT) is a common supraventricular arrhythmia that arises due to a reentrant circuit located in or near the atrioventricular node. This condition ...

Having an accelerated junctional rhythm occurs when the atrioventricular node in your heart beats too quickly. It happens as a result of damage to your heart’s primary natural pacemaker. There’s no ...

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 ...

In this prospective, multicenter clinical trial, we randomly assigned patients with symptomatic, drug-resistant atrial fibrillation, an ejection fraction of 40% or less, and New York Heart Association ...

It’s easy to confuse atrial fibrillation (AFib) with what’s called supraventricular tachycardia (SVT). After all, both have to do with your heart rate and both start in the upper chambers of your ...

Tachycardia is when your heart beats faster than normal, even when you’re not doing anything. Junctional tachycardia is a form of supraventricular tachycardia, a type of racing pulse caused by a ...
