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 ...

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 ...

...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 (AV) nodal ablation with pacing is an alternative therapeutic option in patients with atrial fibrillation (AF) and difficult-to-control ventricular rates that are unresponsive to ...

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

A cardioversion procedure can reset your heart to its normal rhythm. There are two types: Electrical cardioversion. Your doctor gives your heart an electrical shock through paddles or patches on your ...

The largest study comparing the short-term and long-term outcomes of radiofrequency catheter ablation with cryoablation in patients with atrioventricular (AV) nodal re-entrant tachycardia (AVNRT) has ...

A 75-year-old woman presented with dyspnea, an awareness of rapid heart action, and permanent atrial fibrillation with a rapid ventricular response that had been resistant to treatment with ...

The average heart beats 50 to 100 times per minute, pumping blood to the lungs by a sequence of highly organized contractions of the four chambers of our heart. For the heart to function properly, the ...

The atrioventricular node (AV Node) is a bundle of conduction cells that regulate the communication of atrial electrical activity with ventricular electrical activity. The AV node has a long ...

Atrioventricular reentrant tachycardia (AVRT) is a rhythm problem in your heart that makes it beat too fast. It results from an extra connection between your upper and lower chambers. You might hear ...
