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 ...

One approach to this problem has been the use of radiofrequency ablation of the AV node to create complete heart block, followed by implantation of a pacemaker. Symptom relief is good, with attendant ...

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 ...

In patients with atrial fibrillation that is refractory to drug therapy, radio-frequency ablation of the atrioventricular node and implantation of a permanent pacemaker are an alternative therapeutic ...

...little data exist on the use of catheter ablation for AVNRT in elderly patients... Cardiovascular interventional therapies are often withheld from elderly patients, owing to a perceived increase in ...

Atrioventricular nodal reentrant tachycardia (AVNRT) is one of the most commonly encountered arrhythmias worldwide, and catheter ablation remains its treatment of choice. Ablation techniques, ...

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 ...

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 order for the heart to do its work of pumping oxygen-rich blood to the body, it needs a trigger or electrical impulse to generate a heartbeat. This electrical impulse originates from the sinus node ...
