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 ...

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 ...

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 ...

A first-degree atrioventricular node block occurs when conduction through the AV node is slowed, thereby delaying the time it takes for the action potential to travel from the sinoatrial node through ...

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 ...

"Advanced ablation options for electrophysiology" was originally created and published by Medical Device Network, a GlobalData owned brand.

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 ...

A 52-year-old woman presented to the emergency department with palpitations associated with uneasiness and nausea. She was a nonsmoker. She reported having one previous episode of palpitations, ...

...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 ...

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.
