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 ...

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 ...

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 ...

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 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 ...

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.

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 ...

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 ...
