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 ...

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 ...
