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 ...

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 ...

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 ...

Dr. Friedman answers the question: 'What is AV Node Reentrant Tachycardia?' — -- Question: What is AV node reentrant tachycardia, and what is the best way to treat this? Answer :AV node reentrant ...

In second-degree atrioventricular nodal block — also known as Wenckebach block or Mobitz Type I AV block — varying failure of conduction through the AV node occurs, such that some P waves may not be ...

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 ...

Atrioventricular (AV) nodal reentrant tachycardia (AVNRT) is an irregular heart rhythm that can cause excessively fast heart rates. Though not usually serious, early diagnosis can help prevent severe ...

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 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 ...

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 ...
